Donenfeld <Jason@zx2c4.com> # Date: Thu Oct 15 01:02:09 2020 +0200 # # powerpc32: don't adjust unmoved stack pointer in csum_partial_copy_generic() epilogue # # A recent change to the checksum code removed usage of some extra # arguments, alongside with storage on the stack for those, and the stack # pointer no longer needed to be adjusted in the function prologue. # # But a left over subtraction wasn't removed in the function epilogue, # causing the function to return with the stack pointer moved 16 bytes # away from where it should have. This corrupted local state and lead to # weird crashes. # # This simply removes the leftover instruction from the epilogue. # # Fixes: 70d65cd555c5 ("ppc: propagate the calling conventions change down to csum_partial_copy_generic()") # Cc: Al Viro <viro@zeniv.linux.org.uk> # Signed-off-by: Jason A.
