EVP_CIPH_FLAG_LENGTH_BITS flag for CFB1 has been broken with the introduction of the is_partially_overlapping() check that did not take it into the account (treating number of bits passed as bytes). This remedies that and allows this flag to work as intended. Reviewed-by:

While it's always safe to read |SSL_MAX_SSL_SESSION_ID_LENGTH| bytes from an |SSL_SESSION|'s |session_id| array, the hash function would do so with without considering if all those bytes had been written to. This change checks |session_id_length| before possibly reading uninitialised memory. Since the result of the hash function was already attacker controlled, and since a lookup of a short session ID will always fail, it doesn't appear that this is anything more than a clean up. In particular, |ssl_get_prev_session| uses a stack-allocated placeholder |SSL_SESSION| as a lookup key, so the |session_id| array may be uninitialised. This was originally found with libFuzzer and MSan in https://boringssl.googlesource.com/boringssl/+/e976e4349d693b4bbb97e1694f45be5a1b22c8c7 , then by Robert Swiecki with honggfuzz and MSan here. Thanks to both. Reviewed-by:

CFI directives annotate instructions that are significant for stack unwinding procedure. In addition to directives recognized by GNU assembler this module implements three synthetic ones: - .cfi_push annotates push instructions in prologue and translates to .cfi_adjust_cfa_offset (if needed) and .cfi_offset; - .cfi_pop annotates pop instructions in epilogue and translates to .cfi_adjust_cfs_offset (if needed) and .cfi_restore; - .cfi_cfa_expression encodes DW_CFA_def_cfa_expression and passes it to .cfi_escape as byte vector; CFA expression syntax is made up mix of DWARF operator suffixes [subset of] and references to registers with optional bias. Following example describes offloaded original stack pointer at specific offset from current stack pointer: .cfi_cfa_expression %rsp+40,deref,+8 Final +8 has everything to do with the fact that CFA, Canonical Frame Address, is reference to top of caller's stack, and on x86_64 call to subroutine pushes 8-byte return address. Triggered by request from Adam Langley. Reviewed-by: -

When idx is negative (as is the case with do_print_sigalgs in apps/s_cb.c), AddressSanitizer complains about a buffer overflow (read). Even if the pointer is not dereferenced, this is undefined behavior. Change the user not to use "-1" as index since the function is documented to return 0 on out-of-range values. Tested with `openssl s_server` and `curl -k https://localhost:4433`. Reviewed-by:

If s->s3->tmp.new_cipher is NULL then a crash can occur. This can happen if an alert gets sent after version negotiation (i.e. we have selected TLSv1.3 and ended up in tls13_enc), but before a ciphersuite has been selected. Reviewed-by:
