Merge branch 'net-dsa-learning-fixes-for-b53-bcm_sf2'
Florian Fainelli says: ==================== net: dsa: Learning fixes for b53/bcm_sf2 This patch series contains a couple of fixes for the b53/bcm_sf2 drivers with respect to configuring learning. The first patch is wiring-up the necessary dsa_switch_ops operations in order to support the offloading of bridge flags. The second patch corrects the switch driver's default learning behavior which was unfortunately wrong from day one. This is submitted against "net" because this is technically a bug fix since ports should not have had learning enabled by default but given this is dependent upon Vladimir's recent br_flags series, there is no Fixes tag provided. I will be providing targeted stable backports that look a bit different. Changes in v2: - added first patch - updated second patch to include BR_LEARNING check in br_flags_pre as a support bridge flag to offload ==================== Link: https://lore.kernel.org/r/20210222223010.2907234-1-f.fainelli@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> |

net: dsa: b53: Support setting learning on port
Add support for being able to set the learning attribute on port, and make sure that the standalone ports start up with learning disabled. We can remove the code in bcm_sf2 that configured the ports learning attribute because we want the standalone ports to have learning disabled by default and port 7 cannot be bridged, so its learning attribute will not change past its initial configuration.

net: dsa: bcm_sf2: Wire-up br_flags_pre, br_flags and set_mrouter
Because bcm_sf2 implements its own dsa_switch_ops we need to export the
b53_br_flags_pre(), b53_br_flags() and b53_set_mrouter so we can wire-up
them up like they used to be with the former b53_br_egress_floods().

bcm63xx_enet: fix sporadic kernel panic
In ndo_stop functions, netdev_completed_queue() is called during forced
tx reclaim, after netdev_reset_queue(). This may trigger kernel panic if
there is any tx skb left.
This patch moves netdev_reset_queue() to after tx reclaim, so BQL can
complete successfully then reset.

net: icmp: pass zeroed opts from icmp{,v6}_ndo_send before sending
The icmp{,v6}_send functions make all sorts of use of skb->cb, casting
it with IPCB or IP6CB, assuming the skb to have come directly from the
inet layer. But when the packet comes from the ndo layer, especially
when forwarded, there's no telling what might be in skb->cb at that
point. As a result, the icmp sending code risks reading bogus memory
contents, which can result in nasty stack overflows such as this one
reported by a user:
panic+0x108/0x2ea
__stack_chk_fail+0x14/0x20
__icmp_send+0x5bd/0x5c0
icmp_ndo_send+0x148/0x160
In icmp_send, skb->cb is cast with IPCB and an ip_options struct is read
from it. The optlen parameter there is of particular note, as it can
induce writes beyond bounds. There are quite a few ways that can happen
in __ip_options_echo. For example:
// sptr/skb are attacker-controlled skb bytes
sptr = skb_network_header(skb);
// dptr/dopt points to stack memory allocated by __icmp_send
dptr = dopt->__data;
// sopt is the corrupt skb->cb in question
if (sopt->rr) {
optlen = sptr[sopt->rr+1]; // corrupt skb->cb + skb->data
soffset = sptr[sopt->rr+2]; // corrupt skb->cb + skb->data
// this now writes potentially attacker-controlled data, over
// flowing the stack:
memcpy(dptr, sptr+sopt->rr, optlen);
}
In the icmpv6_send case, the story is similar, but not as dire, as only
IP6CB(skb)->iif and IP6CB(skb)->dsthao are used. The dsthao case is
worse than the iif case, but it is passed to ipv6_find_tlv, which does
a bit of bounds checking on the value.
This is easy to simulate by doing a `memset(skb->cb, 0x41,
sizeof(skb->cb));` before calling icmp{,v6}_ndo_send, and it's only by
good fortune and the rarity of icmp sending from that context that we've
avoided reports like this until now. For example, in KASAN:
BUG: KASAN: stack-out-of-bounds in __ip_options_echo+0xa0e/0x12b0
Write of size 38 at addr ffff888006f1f80e by task ping/89
CPU: 2 PID: 89 Comm: ping Not tainted 5.10.0-rc7-debug+ #5

memcpy+0x39/0x60
__ip_options_echo+0xa0e/0x12b0
__icmp_send+0x744/0x1700
Actually, out of the 4 drivers that do this, only gtp zeroed the cb for
the v4 case, while the rest did not. So this commit actually removes the
gtp-specific zeroing, while putting the code where it belongs in the
shared infrastructure of icmp{,v6}_ndo_send.
This commit fixes the issue by passing an empty IPCB or IP6CB along to
the functions that actually do the work. For the icmp_send, this was
already trivial, thanks to __icmp_send providing the plumbing function.
For icmpv6_send, this required a tiny bit of refactoring to make it
behave like the v4 case, after which it was straight forward.

mptcp: do not wakeup listener for MPJ subflows
MPJ subflows are not exposed as fds to user spaces. As such,
incoming MPJ subflows are removed from the accept queue by
tcp_check_req()/tcp_get_cookie_sock().
Later tcp_child_process() invokes subflow_data_ready() on the
parent socket regardless of the subflow kind, leading to poll
wakeups even if the later accept will block.
Address the issue by double-checking the queue state before
waking the user-space.

mptcp: fix DATA_FIN generation on early shutdown
If the msk is closed before sending or receiving any data,
no DATA_FIN is generated, instead an MPC ack packet is
crafted out.
In the above scenario, the MPTCP protocol creates and sends a
pure ack and such packets matches also the criteria for an
MPC ack and the protocol tries first to insert MPC options,
leading to the described error.
This change addresses the issue by avoiding the insertion of an
MPC option for DATA_FIN packets or if the sub-flow is not
established.
To avoid doing multiple times the same test, fetch the data_fin
flag in a bool variable and pass it to both the interested
helpers.

Scheduler updates for v5.12:
[ NOTE: unfortunately this tree had to be freshly rebased today, it's a same-content tree of 82891be90f3c (-next published) merged with v5.11. The main reason for the rebase was an authorship misattribution problem with a new commit, which we noticed in the last minute, and which we didn't want to be merged upstream. The offending commit was deep in the tree, and dependent commits had to be rebased as well. ] - Core scheduler updates: - Add CONFIG_PREEMPT_DYNAMIC: this in its current form adds the preempt=none/voluntary/full boot options (default: full), to allow distros to build a PREEMPT kernel but fall back to close to PREEMPT_VOLUNTARY (or PREEMPT_NONE) runtime scheduling behavior via a boot time selection. There's also the /debug/sched_debug switch to do this runtime. This feature is implemented via runtime patching (a new variant of static calls). The scope of the runtime patching can be best reviewed by looking at the sched_dynamic_update() function in kernel/sched/core.c. ( Note that the dynamic none/voluntary mode isn't 100% identical, for example preempt-RCU is available in all cases, plus the preempt count is maintained in all models, which has runtime overhead even with the code patching. ) The PREEMPT_VOLUNTARY/PREEMPT_NONE models, used by the vast majority of distributions, are supposed to be unaffected. - Fix ignored rescheduling after rcu_eqs_enter(). This is a bug that was found via rcutorture triggering a hang. The bug is that rcu_idle_enter() may wake up a NOCB kthread, but this happens after the last generic need_resched() check. Some cpuidle drivers fix it by chance but many others don't. In true 2020 fashion the original bug fix has grown into a 5-patch scheduler/RCU fix series plus another 16 RCU patches to address the underlying issue of missed preemption events. These are the initial fixes that should fix current incarnations of the bug. - Clean up rbtree usage in the scheduler, by providing & using the following consistent set of rbtree APIs: partial-order; less() based: - rb_add(): add a new entry to the rbtree - rb_add_cached(): like rb_add(), but for a rb_root_cached total-order; cmp() based: - rb_find(): find an entry in an rbtree - rb_find_add(): find an entry, and add if not found - rb_find_first(): find the first (leftmost) matching entry - rb_next_match(): continue from rb_find_first() - rb_for_each(): iterate a sub-tree using the previous two - Improve the SMP/NUMA load-balancer: scan for an idle sibling in a single pass. This is a 4-commit series where each commit improves one aspect of the idle sibling scan logic. - Improve the cpufreq cooling driver by getting the effective CPU utilization metrics from the scheduler - Improve the fair scheduler's active load-balancing logic by reducing the number of active LB attempts & lengthen the load-balancing interval. This improves stress-ng mmapfork performance. - Fix CFS's estimated utilization (util_est) calculation bug that can result in too high utilization values - Misc updates & fixes: - Fix the HRTICK reprogramming & optimization feature - Fix SCHED_SOFTIRQ raising race & warning in the CPU offlining code - Reduce dl_add_task_root_domain() overhead - Fix uprobes refcount bug - Process pending softirqs in flush_smp_call_function_from_idle() - Clean up task priority related defines, remove *USER_*PRIO and USER_PRIO() - Simplify the sched_init_numa() deduplication sort - Documentation updates - Fix EAS bug in update_misfit_status(), which degraded the quality of energy-balancing - Smaller cleanups Signed-off-by: Ingo Molnar <mingo@kernel.org> -----BEGIN PGP SIGNATURE----- iQJFBAABCgAvFiEEBpT5eoXrXCwVQwEKEnMQ0APhK1gFAmAtHBsRHG1pbmdvQGtl cm5lbC5vcmcACgkQEnMQ0APhK1itgg/+NGed12pgPjYBzesdou60Lvx7LZLGjfOt M1F1EnmQGn/hEH2fCY6ZoqIZQTVltm7GIcBNabzYTzlaHZsdtyuDUJBZyj19vTlk zekcj7WVt+qvfjChaNwEJhQ9nnOM/eohMgEOHMAAJd9zlnQvve7NOLQ56UDM+kn/ 9taFJ5ZPvb4avP6C5p3KivvKex6Bjof/Tl0m3utpNyPpI/qK3FyGxwdgCxU0yepT ABWQX5ZQCufFvo1bgnBPfqyzab4MqhoM3bNKBsLQfuAlssG1xRv4KQOev4dRwrt9 pXJikV5C9yez5d2lGe5p0ltH5IZS/l9x2yI/ZQj3OUDTFyV1ic6WfFAqJgDzVF8E i/vvA4NPQiI241Bkps+ErcCw4aVOgiY6TWli74cHjLUIX0+As6aHrFWXGSxUmiHB WR+B8KmdfzRTTlhOxMA+cvlpZcKCfxWkJJmXzr/lDZzIuKPqM3QCE2wD9sixkfVo JNICT0IvZghWOdbMEfZba8Psh/e2LVI9RzdpEiuYJz1ZrVlt1hO0M6jBxY0hMz9n k54z81xODw0a8P2FHMtpmB1vhAeqCmvwA6DO8z0Oxs0DFi+KM2bLf2efHsCKafI+ Bm5v9YFaOk/55R76hJVh+aYLlyFgFkKd+P/niJTPDnxOk3SqJuXvTrql1HeGHkNr kYgQa23dsZk= =pyaG -----END PGP SIGNATURE----- Merge tag 'sched-core-2021-02-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip Pull scheduler updates from Ingo Molnar: "Core scheduler updates: - Add CONFIG_PREEMPT_DYNAMIC: this in its current form adds the preempt=none/voluntary/full boot options (default: full), to allow distros to build a PREEMPT kernel but fall back to close to PREEMPT_VOLUNTARY (or PREEMPT_NONE) runtime scheduling behavior via a boot time selection.

This improves stress-ng mmapfork performance. - Fix CFS's estimated utilization (util_est) calculation bug that can result in too high utilization values Misc updates & fixes: - Fix the HRTICK reprogramming & optimization feature - Fix SCHED_SOFTIRQ raising race & warning in the CPU offlining code - Reduce dl_add_task_root_domain() overhead - Fix uprobes refcount bug - Process pending softirqs in flush_smp_call_function_from_idle() - Clean up task priority related defines, remove *USER_*PRIO and USER_PRIO() - Simplify the sched_init_numa() deduplication sort - Documentation updates - Fix EAS bug in update_misfit_status(), which degraded the quality of energy-balancing - Smaller cleanups" * tag 'sched-core-2021-02-17' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: (51 commits) sched,x86: Allow !PREEMPT_DYNAMIC entry/kvm: Explicitly flush pending rcuog wakeup before last rescheduling point entry: Explicitly flush pending rcuog wakeup before last rescheduling point rcu/nocb: Trigger self-IPI on late deferred wake up before user resume rcu/nocb: Perform deferred wake up before last idle's need_resched() check rcu: Pull deferred rcuog wake up to rcu_eqs_enter() callers sched/features: Distinguish between NORMAL and DEADLINE hrtick sched/features: Fix hrtick reprogramming sched/deadline: Reduce rq lock contention in dl_add_task_root_domain() uprobes: (Re)add missing get_uprobe() in __find_uprobe() smp: Process pending softirqs in flush_smp_call_function_from_idle() sched: Harden PREEMPT_DYNAMIC static_call: Allow module use without exposing static_call_key sched: Add /debug/sched_preempt preempt/dynamic: Support dynamic preempt with preempt= boot option preempt/dynamic: Provide irqentry_exit_cond_resched() static call preempt/dynamic: Provide preempt_schedule[_notrace]() static calls preempt/dynamic: Provide cond_resched() and might_resched() static calls preempt: Introduce CONFIG_PREEMPT_DYNAMIC static_call: Provide DEFINE_STATIC_CALL_RET0() ... |

Remove oprofile and dcookies support

New code for 5.12:
- Fix an ABBA deadlock when renaming files on overlayfs. - Make sure that we can't overflow the inode extent counters when adding to or removing extents from a file. - Make directory sgid inheritance work the same way as all the other filesystems. - Don't drain the buffer cache on freeze and ro remount, which should reduce the amount of time if read-only workloads are continuing during the freeze. - Fix a bug where symlink size isn't reported to the vfs in ecryptfs. - Disentangle log cleaning from log covering. This refactoring sets us up for future changes to the log, though for now it simply means that we can use covering for freezes, and cleaning becomes something we only do at unmount. - Speed up file fsyncs by reducing iolock cycling. - Fix delalloc blocks leaking when changing the project id fails because of input validation errors in FSSETXATTR. - Fix oversized quota reservation when converting unwritten extents during a DAX write. - Create a transaction allocation helper function to standardize the idiom of allocating a transaction, reserving blocks, locking inodes, and reserving quota. Replace all the open-coded logic for file creation, file ownership changes, and file modifications to use them. - Actually shut down the fs if the incore quota reservations get corrupted. - Fix background block garbage collection scans to not block and to actually clean out CoW staging extents properly. - Run block gc scans when we run low on project quota. - Use the standardized transaction allocation helpers to make it so that ENOSPC and EDQUOT errors during reservation will back out, invoke the block gc scanner, and try again. This is preparation for introducing background inode garbage collection in the next cycle. - Combine speculative post-EOF block garbage collection with speculative copy on write block garbage collection. - Enable multithreaded quotacheck. - Allow sysadmins to tweak the CPU affinities and maximum concurrency levels of quotacheck and background blockgc worker pools. - Expose the inode btree counter feature in the fs geometry ioctl. - Cleanups of the growfs code in preparation for starting work on filesystem shrinking. - Fix all the bloody gcc warnings that the maintainer knows about. :P - Fix a RST syntax error. - Don't trigger bmbt corruption assertions after the fs shuts down. - Restore behavior of forcing SIGBUS on a shut down filesystem when someone triggers a mmap write fault (or really, any buffered write). -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEUzaAxoMeQq6m2jMV+H93GTRKtOsFAmAlX/UACgkQ+H93GTRK tOta+RAAiGqLKxeY07HH7F98pRJ86j6lU0zmc5i5UCOGMvZd8hLKDdThzggsjqO6 rrUSc7Ppg7MQt1JdXLSdZw2N6Ksb9yy6chufj+j3Dq1JQfSL4YvBO/LlXmZmFE6d 80Qbqq6HFSRWb6JzCMr3knhC+FJovAGhFgZYZGBZ817A/FXacTg9/A5Ow8SX81WX 42s517QOmegAn7YhC3xcPZp5iavjbMd7Y9v7izpuo4FBB9AY7NYyb5wVhvffILfS /SMLQPw3T/tccRJuVJ8TfLA9R+B9+LaGmQ5tn/AtdwN+Lv7ykinzGKYLagkdlTmE onGkEIwrebEgq9phT47eX7ixiEt7oWQiQGZukXLVn7mL/0WPVI2pbYi/M1BNpi8i UftOEVroav+m4h0DF3duOE7rLGuBIEdjPuuAs85QhZ6UTusBjwxp1gOJbjuN0Up9 9hBGTtYQIRhWxHkxWKAeuYzIbtMxC2S2XGxnW4cNOxbE7GxwfxBw0KP/38ZP4iYQ LKt6JVX+iFDQ+lH8JA6DD7+j+m7W37Alu89OPmpW2nYpFyisFDY+1dEIFvPw9roZ BtbKlZzS2O2zD67/tTVh+ZcPoEcPfp156GDCrgfgdIdiBvQtGbyOLB/WQC6wSU1L 2PLt1inFBx5wNrIEMFMHT1hsduRihNMM+eLn6LV5XIK2RmSCT+I= =CaLz -----END PGP SIGNATURE----- Merge tag 'xfs-5.12-merge-5' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux Pull xfs updates from Darrick Wong: "There's a lot going on this time, which seems about right for this drama-filled year. Community developers added some code to speed up freezing when read-only workloads are still running, refactored the logging code, added checks to prevent file extent counter overflow, reduced iolock cycling to speed up fsync and gc scans, and started the slow march towards supporting filesystem shrinking. There's a huge refactoring of the internal speculative preallocation garbage collection code which fixes a bunch of bugs, makes the gc scheduling per-AG and hence multithreaded, and standardizes the retry logic when we try to reserve space or quota, can't, and want to trigger a gc scan. We also enable multithreaded quotacheck to reduce mount times further. This is also preparation for background file gc, which may or may not land for 5.13. We also fixed some deadlocks in the rename code, fixed a quota accounting leak when FSSETXATTR fails, restored the behavior that write faults to an mmap'd region actually cause a SIGBUS, fixed a bug where sgid directory inheritance wasn't quite working properly, and fixed a bug where symlinks weren't working properly in ecryptfs. We also now advertise the inode btree counters feature that was introduced two cycles ago.

This is useful when a file with fs-verity enabled needs to be served somewhere, and the other end wants to do its own fs-verity compatible verification of the file. See the commit messages for details. This new ioctl has been tested using new xfstests I've written for it. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQSacvsUNc7UX4ntmEPzXCl4vpKOKwUCYCv/2hQcZWJpZ2dlcnNA Z29vZ2xlLmNvbQAKCRDzXCl4vpKOK6/7AQDRmmnV+G34yGPCWfu8tyjdYvWPyak2 IA/I+eM6S/F+4QEAkbX6rOwYVhLHN9KSOYyNhJiBchm6xq83J+R8BYh/Kw0= =FPNK -----END PGP SIGNATURE----- Merge tag 'fsverity-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/fscrypt Pull fsverity updates from Eric Biggers: "Add an ioctl which allows reading fs-verity metadata from a file.

The root cause is that test_bit/set_bit atomic operations are actually implemented in relaxed forms, and uninitialized fields governed by an atomic bit could be observed in advance due to memory reordering thus memory barrier pairs should be used.

f2fs-for-5.12-rc1
We've added two major features: 1) compression level and 2) checkpoint_merge, in this round. 1) compression level expands 'compress_algorithm' mount option to accept parameter as format of <algorithm>:<level>, by this way, it gives a way to allow user to do more specified config on lz4 and zstd compression level, then f2fs compression can provide higher compress ratio. 2) checkpoint_merge creates a kernel daemon and makes it to merge concurrent checkpoint requests as much as possible to eliminate redundant checkpoint issues. Plus, we can eliminate the sluggish issue caused by slow checkpoint operation when the checkpoint is done in a process context in a cgroup having low i/o budget and cpu shares. Enhancement: - add compress level for lz4 and zstd in mount option - checkpoint_merge mount option - deprecate f2fs_trace_io Bug fix: - flush data when enabling checkpoint back - handle corner cases of mount options - missing ACL update and lock for I_LINKABLE flag - attach FIEMAP_EXTENT_MERGED in f2fs_fiemap - fix potential deadlock in compression flow - fix wrong submit_io condition As usual, we've cleaned up many code flows and fixed minor bugs. -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEE00UqedjCtOrGVvQiQBSofoJIUNIFAmAtdrAACgkQQBSofoJI UNLvLg//XWERjTZ3tfHHLtNcIkNCd2WaKXwpanTXJsn0kVUc6H5m8lqkutn5Vh/z ZAtQE89aqwbw/FPQQl6jEA/aHhXAnCBbXS0Rjx7QFwlqs+772H10VLvdNXewgvJB r/u7CIlxbmu3p6ZLSG/a8uJe3CMimJe4lrswjnFlLYgKiho40tcQL8qfQEtkNQSF +MV2npS7ka4x/PenFykVbTI0OcwOpblpgkpjgfl5A9bcOsGbli+1qzcasbcX9z9k 20TwZqk5q7rZHVDjvtYERSyS9mmn3fzEJStK4sdZ6uk+EKxyC+KNHrv9cKwemTCm ZATR/YBJKeYhjYppyYLLTRp5eL08PBNgE15SmnkVRjMcAiFxM689WfShrIVhBaf1 dRr9DxAMLuFSiwFuLBLE/8yMwed38RH9e0RrfQRVjj8Zs2kHcUdwD1WqyDg7omS8 NuH776LhJSsSVgC8ZKTacQgX8l2NvsjAigeBj/6v4o0lzr1msn2ADpQ9Bww9Iqtt lv/09350ww78UV+ipLlVSHw4rl8sebatMUSHtmF4SP7U7Jqv2MaGhNAteWlCklmV 0cTzjEueiuvmrmkiphTHtl1fHHDVCE0xtScpoylchPVd8bal0pVq4XbZLmGsQwDt 9V9qOebt2xLmx9EXDyqdRWRbDrtE0FG/AZiN8Q0VcJSzUI/ATx8= =+/7T -----END PGP SIGNATURE----- Merge tag 'f2fs-for-5.12-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/jaegeuk/f2fs Pull f2fs updates from Jaegeuk Kim: "We've added two major features: 1) compression level and 2) checkpoint_merge, in this round.
