Subject: [PATCH] upstream: when receving a file in sink(), be careful to send
at
most a single error response after the file has been opened. Otherwise the
source() and sink() can become desyncronised. Reported by Daniel Goujot,
Georges-Axel Jaloyan, Ryan Lahfa, and David Naccache.

Subject: Move closefrom() to before first malloc.
When built against tcmalloc, tcmalloc allocates a descriptor for its
internal use, so calling closefrom() afterward causes the descriptor
number to be reused resulting in a corrupted connection. Moving the
closefrom a little earlier should resolve this. From kircherlike at

Subject: [PATCH] upstream: Refactor private key parsing. Eliminates a fair bit
of
duplicated code and fixes oss-fuzz#20074 (NULL deref) caused by a missing key
type check in the ECDSA_CERT parsing path.
