[PATCH openEuler-1.0-LTS] printk: Skip log flush in NMI context when logbuf_lock is held
by Xiaomeng Zhang 31 Dec '24

hulk inclusion
category: bugfix
bugzilla: https://gitee.com/openeuler/kernel/issues/IB963V
CVE: NA
--------------------------------
In nmi_trigger_cpumask_backtrace(), printk_safe_flush() is called after
sending NMI to flush the logs. When logbuf_lock is already held and the
current CPU is in printk-safe context (e.g., NMI context), attempting to
acquire the lock again can lead to deadlock.
Modify the function to return early when detecting logbuf_lock is held
and current CPU is in printk-safe context. This prevents deadlock scenarios
where CPU0 holds the lock while other CPUs try to acquire it in NMI
context.
Fixes: 099f1c84c005 ("printk: introduce per-cpu safe_print seq buffer")

category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBEGFD
CVE: CVE-2024-56748
Reference: https://git.kernel.org/stable/c/a56777a3ef5b35e24a20c4418bcf88bad033807a
--------------------------------
[ Upstream commit c62c30429db3eb4ced35c7fcf6f04a61ce3a01bb ]
Hook "qed_ops->common->sb_init = qed_sb_init" does not release the DMA
memory sb_virt when it fails. Add dma_free_coherent() to free it. This
is the same way as qedr_alloc_mem_sb() and qede_alloc_mem_sb().

CVE: NA
--------------------------------
Suppose existing call chain: P() -> A() -> B(), B() don't construct stack
frame in which fp and lr are saved for call stack unwinding, then if task1
is interrupted as running at address 'B2' and then preempted by task2,
and task2 unwind the call stack of task1, it expect to see P->A->B, but
actually P->B, A disappeared!
A():
A1: stp fp, lr, ... <-- suppose fp_P and lr_P saved
A2: mov fp, sp <-- suppose fp_A saved in 'fp' register
A3: bl B <-- call to B()
A4: mov ... <-- 'A4' saved in 'lr' register
B():
B1: mov ...
B2: mov ... <-- interrupt comes, then run into el1_irq()
B3: mov ... <-- 'B3' is saved in 'elr_el1' register
el1_irq():
... <-- save registers then construct stack frame
Cm: bl arm64_preempt_schedule_irq <-- Can be preempted here
Cn: ...
In this case, at the time interrupt comes, the address 'A4' will be saved
In 'lr' register, then in interrupt entry, 'lr' register will be saved in
Stack memory as struct pt_regs.
See following stack memory layout, as call stack unwinding, if address
'Cn' is found , we know that fp_C is point to pt_regs.stackframe[0],
then we can found the 'A4' in pt_regs.regs[30], then we can know that
B() is currently called by A().
Stack memory (High address downto Low address):
<High address>

| lr_P |
|-----------------|
| fp_P |
-> |-----------------|
| | ... |
| |-----------------|
| | B3 |
