Revision ab1016d39cc052064e32f25ad18ef8767a0ee3b8 authored by J. Bruce Fields on 02 July 2021, 00:06:56 UTC, committed by J. Bruce Fields on 07 July 2021, 00:14:44 UTC
In error cases the dentry may be NULL. Before 20798dfe249a, the encoder also checked dentry and d_really_is_positive(dentry), but that looks like overkill to me--zero status should be enough to guarantee a positive dentry. This isn't the first time we've seen an error-case NULL dereference hidden in the initialization of a local variable in an xdr encoder. But I went back through the other recent rewrites and didn't spot any similar bugs.
