2022-07-25net: mld: fix reference count leak in mld_{query | report}_work()Taehee Yoo1-6/+8
mld_{query | report}_work() processes queued events. If there are too many events in the queue, it re-queue a work. And then, it returns without in6_dev_put(). But if queuing is failed, it should call in6_dev_put(), but it doesn't. So, a reference count leak would occur.

2022-07-25net: macb: Update tsu clk usage in runtime suspend/resume for VersalHarini Katakam2-2/+16
On Versal TSU clock cannot be disabled irrespective of whether PTP is used. Hence introduce a new Versal config structure with a "need tsu" caps flag and check the same in runtime_suspend/resume before cutting off clocks. More information on this for future reference: This is an IP limitation on versions 1p11 and 1p12 when Qbv is enabled (See designcfg1, bit 3). However it is better to rely on an SoC specific check rather than the IP version because tsu clk property itself may not represent actual HW tsu clock on some chip designs.

2022-07-25net: macsec: fix potential resource leak in macsec_add_rxsa() and ↵Jianglei Nie1-2/+2
macsec_add_txsa() init_rx_sa() allocates relevant resource for rx_sa->stats and rx_sa-> key.tfm with alloc_percpu() and macsec_alloc_tfm(). When some error occurs after init_rx_sa() is called in macsec_add_rxsa(), the function released rx_sa with kfree() without releasing rx_sa->stats and rx_sa-> key.tfm, which will lead to a resource leak. We should call macsec_rxsa_put() instead of kfree() to decrease the ref count of rx_sa and release the relevant resource if the refcount is 0. The same bug exists in macsec_add_txsa() for tx_sa as well. This patch fixes the above two bugs.

2022-07-25macsec: always read MACSEC_SA_ATTR_PN as a u64Sabrina Dubroca1-3/+3
Currently, MACSEC_SA_ATTR_PN is handled inconsistently, sometimes as a u32, sometimes forced into a u64 without checking the actual length of the attribute. Instead, we can use nla_get_u64 everywhere, which will read up to 64 bits into a u64, capped by the actual length of the attribute coming from userspace. This fixes several issues: - the check in validate_add_rxsa doesn't work with 32-bit attributes - the checks in validate_add_txsa and validate_upd_sa incorrectly reject X << 32 (with X != 0) Fixes: 48ef50fa866a ("macsec: Netlink support of XPN cipher suites (IEEE 802.1AEbw)") Signed-off-by: Sabrina Dubroca <sd@queasysnail.net> Signed-off-by: David S.

2022-07-25macsec: limit replay window size with XPNSabrina Dubroca1-4/+12
IEEE 802.1AEbw-2013 (section 10.7.8) specifies that the maximum value of the replay window is 2^30-1, to help with recovery of the upper bits of the PN. To avoid leaving the existing macsec device in an inconsistent state if this test fails during changelink, reuse the cleanup mechanism introduced for HW offload. This wasn't needed until now because macsec_changelink_common could not fail during changelink, as modifying the cipher suite was not allowed. Finally, this must happen after handling IFLA_MACSEC_CIPHER_SUITE so that secy->xpn is set.

Commit 48ef50fa866a added a test on tb_sa[MACSEC_SA_ATTR_PN], but nothing guarantees that it's not NULL at this point. The same code was added to macsec_add_txsa, but there it's not a problem because validate_add_txsa checks that the MACSEC_SA_ATTR_PN attribute is present. Note: it's not possible to reproduce with iproute, because iproute doesn't allow creating an SA without specifying the PN.

2022-07-24net/tls: Remove the context from the list in tls_device_downMaxim Mikityanskiy1-1/+6
tls_device_down takes a reference on all contexts it's going to move to the degraded state (software fallback). If sk_destruct runs afterwards, it can reduce the reference counter back to 1 and return early without destroying the context. Then tls_device_down will release the reference it took and call tls_device_free_ctx. However, the context will still stay in tls_device_down_list forever. The list will contain an item, memory for which is released, making a memory corruption possible. Fix the above bug by properly removing the context from all lists before any call to tls_device_free_ctx.

2022-07-23Bluetooth: btusb: Detect if an ACL packet is in fact an ISO packetLuiz Augusto von Dentz1-0/+10
Fix up the packet type if ISO packets are sent over the bulk endpoint. Note: This is a stopgap since the Bluetooth specification currently doesn't define any endpoint to transport ISO packets. Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

2022-07-23Bluetooth: ISO: Add broadcast supportLuiz Augusto von Dentz3-34/+370
This adds broadcast support for BTPROTO_ISO by extending the sockaddr_iso with a new struct sockaddr_iso_bc where the socket user can set the broadcast address when receiving, the SID and the BIS indexes it wants to synchronize. When using BTPROTO_ISO for broadcast the roles are: Broadcaster -> uses connect with address set to BDADDR_ANY: > tools/isotest -s 00:00:00:00:00:00 Broadcast Receiver -> uses listen with address set to broadcaster: > tools/isotest -d 00:AA:01:00:00:00 Signed-off-by: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>
