[PATCH openEuler-1.0-LTS v2] fs:/dcache.c: fix negative dentry limit not complete problem
by Long Li 29 Jan '24
by Long Li 29 Jan '24
29 Jan '24
hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/I8WPQW
CVE: NA
--------------------------------
Restrictions of negative dentry can avoid softlock when too many dentry in
memory, but restrictions before do not always take effect. For example,
removing files which has been created would not enter retain_dentry(),
because the dentry of file maybe has been added to lru list of superblock,
it caused that fast_dput() reutrn true in last dput().
So, add restriction logic for the file which has been added to the lru list
in fast_dput(), it prevents the negative dentry exceeding the limit when
deleting existing file. Factor out negative dentry limit logic into
limit_negative_dentry(), make the code more clean.
Fixes: 7ba5d5d0e8b5 ("fs/dcache.c: avoid softlock since too many negative dentry")

KABI reservation for IMA and crypto module.
v3:
Reserve one more u64 for crypto related structs.
v2:
Changed reservation ordering, and more reservation.

bugzilla: https://gitee.com/openeuler/kernel/issues/I8ZE0I
CVE: NA
---------------------------------
There is softlockup under fio pressure test with smmu enabled:
watchdog: BUG: soft lockup - CPU#81 stuck for 22s! [swapper/81:0]
...
Call trace:
fq_flush_timeout+0xc0/0x110
call_timer_fn+0x34/0x178
expire_timers+0xec/0x158
run_timer_softirq+0xc0/0x1f8

do_idle+0x1f4/0x2d8
cpu_startup_entry+0x2c/0x30
secondary_start_kernel+0x17c/0x1c8
This is because the timer callback fq_flush_timeout may run more than
10ms, and timer may be processed continuously in the softirq so trigger
softlockup. We can use work to deal with fq_ring_free for each cpu which
may take long time, that to avoid triggering softlockup.
