The eventfd syscall is deprecated and is not available on aarch64, causing build to fail: engines/e_afalg.c: In function 'eventfd': engines/e_afalg.c:108:20: error: '__NR_eventfd' undeclared (first use in this function) return syscall(__NR_eventfd, n); ^ Instead, switch to the newer eventfd2 syscall, which is supposed to be supported by all architectures.

If the list of fds contains only (one or more) entries marked as deleted prior to the entry currently being deleted, and the entry currently being deleted was only just added, the 'prev' pointer would never be updated from its initial NULL value, and we would dereference NULL while trying to remove the entry from the linked list.

We currently increment the SSL_CTX stats.sess_accept field in tls_setup_handshake(), which is invoked from the state machine well before ClientHello processing would have had a chance to switch the SSL_CTX attached to the SSL object due to a provided SNI value. However, stats.sess_accept_good is incremented in tls_finish_handshake(), and uses the s->ctx.stats field (i.e., the new SSL_CTX that was switched to as a result of SNI processing). This leads to the confusing (nonsensical) situation where stats.sess_accept_good is larger than stats.sess_accept, as the "sess_accept" value was counted on the s->session_ctx. In order to provide some more useful numbers, increment s->ctx.stats.sess_accept after SNI processing if the SNI processing changed s->ctx to differ from s->session_ctx. To preserve the property that any given accept is counted only once, make the corresponding decrement to s->session_ctx.stats.sess_accept when doing so. Reviewed-by:

For client SSL objects and before any callbacks have had a chance to be called, we can write the stats accesses using the session_ctx, which makes sense given that these values are all prefixed with "sess_". For servers after a client_hello or servername callback has been called, retain the existing behavior of modifying the statistics for the current (non-session) context. This has some value, in that it allows the statistics to be viewed on a per-vhost level. Reviewed-by:

It is expected that SSL_CTX objects are shared across threads, and as such we are responsible for ensuring coherent data accesses. Aligned integer accesses ought to be atomic already on all supported architectures, but we can be formally correct. Reviewed-by:

The functions strcasecmp() and strncasecmp() will use locale specific rules when performing comparison. This could cause some problems in certain locales. For example in the Turkish locale an 'I' character is not the uppercase version of 'i'. However IA5 strings should not use locale specific rules, i.e. for an IA5 string 'I' is uppercase 'i' even if using the Turkish locale. This fixes a bug in name constraints checking reported by Thomas Pornin (NCCGroup). This is not considered a security issue because it would require both a Turkish locale (or other locale with similar issues) and malfeasance by a trusted name-constrained CA for a certificate to pass name constraints in error. The constraints also have to be for excluded sub-trees which are extremely rare. Failure to match permitted subtrees is a bug, not a vulnerability. Reviewed-by:

asn1_item_embed_free() will try unlocking and fail in this case, and since the new item was just allocated on the heap, free it directly with OPENSSL_free() instead. Reviewed-by:

Richard Levitte authored
The previous change with this intention didn't quite do it. An embedded item must not be freed itself, but might potentially contain non-embedded elements, which must be freed. So instead of calling ASN1_item_ex_free(), where we can't pass the embed flag, we call asn1_item_embed_free() directly. This changes asn1_item_embed_free() from being a static function to being a private non-static function. Reviewed-by:

The lhash expand() function can fail if realloc fails. The previous implementation made changes to the structure and then attempted to do a realloc. If the realloc failed then it attempted to undo the changes it had just made. Unfortunately changes to lh->p were not undone correctly, ultimately causing subsequent expand() calls to increment num_nodes to a value higher than num_alloc_nodes, which can cause out-of-bounds reads/ writes. This is not considered a security issue because an attacker cannot cause realloc to fail. This commit moves the realloc call to near the beginning of the function before any other changes are made to the lhash structure. That way if a failure occurs we can immediately fail without having to undo anything. Thanks to Pavel Kopyl (Samsung) for reporting this issue. Reviewed-by:

The drbg's lock must be held across calls to RAND_DRBG_generate() to prevent simultaneous modification of internal state. This was observed in practice with simultaneous SSL_new() calls attempting to seed the (separate) per-SSL RAND_DRBG instances from the global rand_drbg instance; this eventually led to simultaneous calls to ctr_BCC_update() attempting to increment drbg->bltmp_pos for their respective partial final block, violating the invariant that bltmp_pos < 16. The AES operations performed in ctr_BCC_blocks() makes the race window quite easy to trigger. A value of bltmp_pos greater than 16 induces catastrophic failure in ctr_BCC_final(), with subtraction overflowing and leading to an attempt to memset() to zero a very large range, which eventually reaches an unmapped page and segfaults. Provide the needed locking in get_entropy_from_parent(), as well as fixing a similar issue in RAND_priv_bytes(). There is also an unlocked call to RAND_DRBG_generate() in ssl_randbytes(), but the requisite serialization is already guaranteed by the requirements on the application's usage of SSL objects, and no further locking is needed for correct behavior. In that case, leave a comment noting the apparent discrepancy and the reason for its safety (at present). Reviewed-by:
