2021-01-07chtls: Fix chtls resources release sequenceAyush Sawal1-4/+4
CPL_ABORT_RPL is sent after releasing the resources by calling chtls_release_resources(sk); and chtls_conn_done(sk); eventually causing kernel panic. Fixing it by calling release in appropriate order.

2021-01-07chtls: Replace skb_dequeue with skb_peekAyush Sawal1-1/+1
The skb is unlinked twice, one in __skb_dequeue in function chtls_reset_synq() and another in cleanup_syn_rcv_conn(). So in this patch using skb_peek() instead of __skb_dequeue(), so that unlink will be handled only in cleanup_syn_rcv_conn().

This patch was discussed both with Herbert Xu (representing team netdev) and James Morris (representing team LSMs-other-than-SELinux). - Fix how we handle errors in inode_doinit_with_dentry() so that we attempt to properly label the inode on following lookups instead of continuing to treat it as unlabeled. - Tweak the kernel logic around allowx, auditallowx, and dontauditx SELinux policy statements such that the auditx/dontauditx are effective even without the allowx statement.

The "skb" is freed by the transmit code in cxgb4_ofld_send() and we shouldn't use it again. But in the current code, if we hit an error later on in the function then the clean up code will call kfree_skb(skb) and so it causes a double free.

2020-11-20crypto: sha - split sha.h into sha1.h and sha2.hEric Biggers2-2/+4
Currently <crypto/sha.h> contains declarations for both SHA-1 and SHA-2, and <crypto/sha3.h> contains declarations for SHA-3. This organization is inconsistent, but more importantly SHA-1 is no longer considered to be cryptographically secure. So to the extent possible, SHA-1 shouldn't be grouped together with any of the other SHA versions, and usage of it should be phased out. Therefore, split <crypto/sha.h> into two headers <crypto/sha1.h> and <crypto/sha2.h>, and make everyone explicitly specify whether they want the declarations for SHA-1, SHA-2, or both. This avoids making the SHA-1 declarations visible to files that don't want anything to do with SHA-1. It also prepares for potentially moving sha1.h into a new insecure/ or dangerous/ directory.

2020-11-11cxgb4/ch_ktls: creating skbs causes panicRohit Maheshwari3-169/+226
Creating SKB per tls record and freeing the original one causes panic. There will be race if connection reset is requested. By freeing original skb, refcnt will be decremented and that means, there is no pending record to send, and so tls_dev_del will be requested in control path while SKB of related connection is in queue. Better approach is to use same SKB to send one record (partial data) at a time. We still have to create a new SKB when partial last part of a record is requested. This fix introduces new API cxgb4_write_partial_sgl() to send partial part of skb. Present cxgb4_write_sgl can only provide feasibility to start from an offset which limits to header only and it can write sgls for the whole skb len. But this new API will help in both. It can start from any offset and can end writing in middle of the skb. v4->v5: - Removed extra changes.

2020-11-03chelsio/chtls: fix always leaking ctrl_skbVinay Kumar Yadav1-1/+1
Correct skb refcount in alloc_ctrl_skb(), causing skb memleak when chtls_send_abort() called with NULL skb. it was always leaking the skb, correct it by incrementing skb refs by one.

2020-11-03chelsio/chtls: fix memory leaks caused by a raceVinay Kumar Yadav1-0/+3
race between user context and softirq causing memleak, consider the call sequence scenario chtls_setkey() //user context chtls_peer_close() chtls_abort_req_rss() chtls_setkey() //user context work request skb queued in chtls_setkey() won't be freed because resources are already cleaned for this connection, fix it by not queuing work request while socket is closing. v1->v2: - fix W=1 warning. v2->v3: - separate it out from another memleak fix.

In chtls_pass_establish() we hold child socket lock using bh_lock_sock and we are again trying bh_lock_sock in add_to_reap_list, causing deadlock. Remove bh_lock_sock in add_to_reap_list() as lock is already held.

2020-10-26cxgb4: set up filter action after rewritesRaju Rangoju2-29/+31
The current code sets up the filter action field before rewrites are set up. When the action 'switch' is used with rewrites, this may result in initial few packets that get switched out don't have rewrites applied on them. So, make sure filter action is set up along with rewrites or only after everything else is set up for rewrites.

chtls_pt_recvmsg() receives a skb with tls header and subsequent skb with data, need to finalize the data copy whenever next skb with tls header is available. but here current tls header is overwritten by next available tls header, ends up corrupting user buffer data. fixing it by finalizing current record whenever next skb contains tls header. v1->v2: - Improved commit message.

2020-10-20net: chelsio: inline_crypto: fix Kconfig and build errorsRandy Dunlap1-0/+1
Fix build errors when TLS=m, TLS_TOE=y, and CRYPTO_DEV_CHELSIO_TLS=y. Having (tristate) CRYPTO_DEV_CHELSIO_TLS depend on (bool) TLS_TOE is not strong enough to prevent the bad combination of TLS=m and CRYPTO_DEV_CHELSIO_TLS=y, so add a dependency on TLS to prevent the problematic kconfig combination.

When chtls_sock *csk is freed, same memory can be allocated to different csk in chtls_sock_create(). csk->cdev = NULL; statement might ends up modifying wrong csk, eventually causing kernel panic. removing (csk->cdev = NULL) statement as it is not required.
