[PATCH 5.4.y] tracing/kprobe: Fix to support kretprobe events on unloaded modules

by Masami Hiramatsu

commit 97c753e62e6c31a404183898d950d8c08d752dbd upstream. Fix kprobe_on_func_entry() returns error code instead of false so that register_kretprobe() can return an appropriate error code. append_trace_kprobe() expects the kprobe registration returns -ENOENT when the target symbol is not found, and it checks whether the target module is unloaded or not. If the target module doesn't exist, it defers to probe the target symbol until the module is loaded. However, since register_kretprobe() returns -EINVAL instead of -ENOENT in that case, it always fail on putting the kretprobe event on unloaded modules. e.g. Kprobe event: /sys/kernel/debug/tracing # echo p xfs:xfs_end_io >> kprobe_events [ 16.515574] trace_kprobe: This probe might be able to register after target module is loaded. Continue. Kretprobe event: (p -> r) /sys/kernel/debug/tracing # echo r xfs:xfs_end_io >> kprobe_events sh: write error: Invalid argument /sys/kernel/debug/tracing # cat error_log [ 41.122514] trace_kprobe: error: Failed to register probe event Command: r xfs:xfs_end_io ^ To fix this bug, change kprobe_on_func_entry() to detect symbol lookup failure and return -ENOENT in that case. Otherwise it returns -EINVAL or 0 (succeeded, given address is on the entry).

[RFC][PATCH 01/13] mm/vmscan: restore zone_reclaim_mode ABI

by Dave Hansen

From: Dave Hansen <dave.hansen(a)linux.intel.com> I went to go add a new RECLAIM_* mode for the zone_reclaim_mode sysctl. Like a good kernel developer, I also went to go update the documentation. I noticed that the bits in the documentation didn't match the bits in the #defines. The VM never explicitly checks the RECLAIM_ZONE bit. The bit is, however implicitly checked when checking 'node_reclaim_mode==0'. The RECLAIM_ZONE #define was removed in a cleanup. That, by itself is fine. But, when the bit was removed (bit 0) the _other_ bit locations also got changed. That's not OK because the bit values are documented to mean one specific thing and users surely rely on them meaning that one thing and not changing from kernel to kernel. The end result is that if someone had a script that did: sysctl vm.zone_reclaim_mode=1 This script would have gone from enalbing node reclaim for clean unmapped pages to writing out pages during node reclaim after the commit in question. That's not great. Put the bits back the way they were and add a comment so something like this is a bit harder to do again. Update the documentation to make it clear that the first bit is ignored.

patch "phy: lantiq: rcu-usb2: wait after clock enable" added to char-misc-testing

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled phy: lantiq: rcu-usb2: wait after clock enable to my char-misc git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc.git in the char-misc-testing branch. The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.) The patch will be merged to the char-misc-next branch sometime soon, after it passes testing, and the merge window is open. If you have any questions about this process, please let me know. >From 36acd5e24e3000691fb8d1ee31cf959cb1582d35 Mon Sep 17 00:00:00 2001 From: Mathias Kresin <dev(a)kresin.me> Date: Thu, 7 Jan 2021 23:49:01 +0100 Subject: phy: lantiq: rcu-usb2: wait after clock enable Commit 65dc2e725286 ("usb: dwc2: Update Core Reset programming flow.") revealed that the phy isn't ready immediately after enabling it's clocks.

[PATCH] gfs2: Recursive gfs2_quota_hold in gfs2_iomap_end

by Andreas Gruenbacher

When starting an iomap write, gfs2_quota_lock_check -> gfs2_quota_lock -> gfs2_quota_hold is called from gfs2_iomap_begin. At the end of the write, before unlocking the quotas, punch_hole -> gfs2_quota_hold can be called again in gfs2_iomap_end, which is incorrect and leads to a failed assertion. Instead, move the call to gfs2_quota_unlock before the call to punch_hole to fix that.
