2023-05-24xen/blkfront: Only check REQ_FUA for writesRoss Lagerwall1-1/+2
The existing code silently converts read operations with the REQ_FUA bit set into write-barrier operations. This results in data loss as the backend scribbles zeroes over the data instead of returning it. While the REQ_FUA bit doesn't make sense on a read operation, at least one well-known out-of-tree kernel module does set it and since it results in data loss, let's be safe here and only look at REQ_FUA for writes.

2023-04-25xen/blkback: move blkif_get_x86_*_req() into blkback.cJuergen Gross2-96/+104
There is no need to have the functions blkif_get_x86_32_req() and blkif_get_x86_64_req() in a header file, as they are used in one place only. So move them into the using source file and drop the inline qualifier. While at it fix some style issues, and simplify the code by variable reusing and using min() instead of open coding it. Instead of using barrier() use READ_ONCE() for avoiding multiple reads of nr_segments.

bind_evtchn_to_irqhandler() shouldn't be called under spinlock, as it can sleep. This requires to move the calls of create_active() out of the locked regions. This is no problem, as the worst which could happen would be a spurious call of the interrupt handler, causing a spurious wake_up().

2023-04-23gcc: disable '-Warray-bounds' for gcc-13 tooLinus Torvalds1-7/+3
We started disabling '-Warray-bounds' for gcc-12 originally on s390, because it resulted in some warnings that weren't realistically fixable (commit 8b202ee21839: "s390: disable -Warray-bounds"). That s390-specific issue was then found to be less common elsewhere, but generic (see f0be87c42cbd: "gcc-12: disable '-Warray-bounds' universally for now"), and then later expanded the version check was expanded to gcc-11 (5a41237ad1d4: "gcc: disable -Warray-bounds for gcc-11 too"). And it turns out that I was much too optimistic in thinking that it's all going to go away, and here we are with gcc-13 showing all the same issues. So instead of expanding this one version at a time, let's just disable it for gcc-11+, and put an end limit to it only when we actually find a solution. Yes, I'm sure some of this is because the kernel just does odd things (like our "container_of()" use, but also knowingly playing games with things like linker tables and array layouts). And yes, some of the warnings are likely signs of real bugs, but when there are hundreds of false positives, that doesn't really help. Oh well.

2023-04-23kbuild: use proper prefix for tarballs to fix rpm-pkg build errorMasahiro Yamada1-3/+3
Since commit f8d94c4e403c ("kbuild: do not create intermediate *.tar for source tarballs"), 'make rpm-pkg' fails because the prefix of the source tarball is 'linux.tar/' instead of 'linux/'. $(basename $@) strips only '.gz' from the filename linux.tar.gz. You need to strip two suffixes from compressed tarballs and one suffix from uncompressed tarballs (for example 'perf-6.3.0.tar' generated by 'make perf-tar-src-pkg'). One tricky fix might be --prefix=$(firstword $(subst .tar, ,$@))/ but I think it is better to hard-code the prefix.

2023-04-21btrfs: reinterpret async discard iops_limit=0 as no delayBoris Burkov1-7/+12
Currently, a limit of 0 results in a hard coded metering over 6 hours. Since the default is a set limit, I suspect no one truly depends on this rather arbitrary setting. Repurpose it for an arguably more useful "unlimited" mode, where the delay is 0. Note that if block groups are too new, or go fully empty, there is still a delay associated with those conditions. Those delays implement heuristics for not trimming a region we are relatively likely to fully overwrite soon.

2023-04-21btrfs: set default discard iops_limit to 1000Boris Burkov1-1/+1
Previously, the default was a relatively conservative 10. This results in a 100ms delay, so with ~300 discards in a commit, it takes the full 30s till the next commit to finish the discards. On a workstation, this results in the disk never going idle, wasting power/battery, etc. Set the default to 1000, which results in using the smallest possible delay, currently, which is 1ms. This has shown to not pathologically keep the disk busy by the original reporter.

2023-04-20PCI: Restrict device disabled status check to DTRob Herring3-12/+30
Commit 6fffbc7ae137 ("PCI: Honor firmware's device disabled status") checked the firmware device status for both DT and ACPI devices. That caused a regression in some ACPI systems. The exact reason isn't clear. It's possibly a firmware bug. For now, at least, refactor the check to be for DT based systems only. Note that the original implementation leaked a refcount which is now correctly handled.

2023-04-20net: bridge: switchdev: don't notify FDB entries with "master dynamic"Vladimir Oltean1-0/+11
There is a structural problem in switchdev, where the flag bits in struct switchdev_notifier_fdb_info (added_by_user, is_local etc) only represent a simplified / denatured view of what's in struct net_bridge_fdb_entry :: flags (BR_FDB_ADDED_BY_USER, BR_FDB_LOCAL etc). Each time we want to pass more information about struct net_bridge_fdb_entry :: flags to struct switchdev_notifier_fdb_info (here, BR_FDB_STATIC), we find that FDB entries were already notified to switchdev with no regard to this flag, and thus, switchdev drivers had no indication whether the notified entries were static or not. For example, this command: ip link add br0 type bridge && ip link set swp0 master br0 bridge fdb add dev swp0 00:01:02:03:04:05 master dynamic has never worked as intended with switchdev. It causes a struct net_bridge_fdb_entry to be passed to br_switchdev_fdb_notify() which has a single flag set: BR_FDB_ADDED_BY_USER. This is further passed to the switchdev notifier chain, where interested drivers have no choice but to assume this is a static (does not age) and sticky (does not migrate) FDB entry. So currently, all drivers offload it to hardware as such, as can be seen below ("offload" is set). bridge fdb get 00:01:02:03:04:05 dev swp0 master 00:01:02:03:04:05 dev swp0 offload master br0 The software FDB entry expires $ageing_time centiseconds after the kernel last sees a packet with this MAC SA, and the bridge notifies its deletion as well, so it eventually disappears from hardware too. This is a problem, because it is actually desirable to start offloading "master dynamic" FDB entries correctly - they should expire $ageing_time centiseconds after the *hardware* port last sees a packet with this MAC SA - and this is how the current incorrect behavior was discovered. With an offloaded data plane, it can be expected that software only sees exception path packets, so an otherwise active dynamic FDB entry would be aged out by software sooner than it should. With the change in place, these FDB entries are no longer offloaded: bridge fdb get 00:01:02:03:04:05 dev swp0 master 00:01:02:03:04:05 dev swp0 master br0 and this also constitutes a better way (assuming a backport to stable kernels) for user space to determine whether the kernel has the capability of doing something sane with these or not. As opposed to "master dynamic" FDB entries, on the current behavior of which no one currently depends on (which can be deduced from the lack of kselftests), Ido Schimmel explains that entries with the "extern_learn" flag (BR_FDB_ADDED_BY_EXT_LEARN) should still be notified to switchdev, since the spectrum driver listens to them (and this is kind of okay, because although they are treated identically to "static", they are expected to not age, and to roam).
