baf76f0c58aec435a3a864075b8f6d8ee5d1f17e # Author: Linus Torvalds <torvalds@linux-foundation.org> # Date: Thu Apr 25 16:13:58 2019 -0700 # # slip: make slhc_free() silently accept an error pointer # # This way, slhc_free() accepts what slhc_init() returns, whether that is # an error or not. # # In particular, the pattern in sl_alloc_bufs() is # # slcomp = slhc_init(16, 16); # ... # slhc_free(slcomp); # # for the error handling path, and rather than complicate that code, just # make it ok to always free what was returned by the init function. # # That's what the code used to do before commit 4ab42d78e37a ("ppp, slip: # Validate VJ compression slot parameters completely") when slhc_init() # just returned NULL for the error case, with no actual indication of the # details of the error. # # Reported-by: syzbot+45474c076a4927533d2e@syzkaller.appspotmail.com # Fixes: 4ab42d78e37a ("ppp, slip: Validate VJ compression slot parameters completely") # Acked-by: Ben Hutchings
