CVE-2024-41081: ila: block BH in ila_output()
In the Linux kernel, the following vulnerability has been resolved:
ila: block BH in ilaoutput()
As explained in commit 1378817486d6 ("tipc: block BH before using dstcache"), net/core/dstcache.c helpers need to be called with BH disabled.
ilaoutput() is called from lwtunneloutput() possibly from process context, and under rcureadlock().
We might be interrupted by a softirq, re-enter ilaoutput() and corrupt dstcache data structures.
Fix the race by using localbhdisable().
