[ Upstream commit 765bb861 ] When CONFIG_DVB_DIB9000 is disabled, we can still compile code that now fails to link against dibx000_i2c_set_speed: drivers/media/usb/dvb-usb/dib0700_devices.o: In function `dib01x0_pmu_update.constprop.7': dib0700_devices.c:(.text.unlikely+0x1c9c): undefined reference to `dibx000_i2c_set_speed' The call sites are both through dib01x0_pmu_update(), which gets passed an 'i2c' pointer from dib9000_get_i2c_master(), which has returned NULL. Checking this pointer seems to be a good idea anyway, and it avoids the link failure in most cases. Sean Young found another case that is not fixed by that, where certain gcc versions leave an unused function in place that causes the link error, but adding an explict IS_ENABLED() check also solves this.

[ Upstream commit 6e37ccf7 ] We need to use the proper types and convert between physical addresses and dma addresses here to avoid mismatch warnings. This is especially important on systems with a different size for dma addresses and physical addresses. Otherwise, we get the following warning: drivers/firmware/qcom_scm.c: In function "qcom_scm_assign_mem": drivers/firmware/qcom_scm.c:469:47: error: passing argument 3 of "dma_alloc_coherent" from incompatible pointer type [-Werror=incompatible-pointer-types] We also fix the size argument to dma_free_coherent() because that size doesn't need to be aligned after it's already aligned on the allocation size. In fact, dma debugging expects the same arguments to be passed to both the allocation and freeing sides of the functions so changing the size is incorrect regardless. Reported-by:

[ Upstream commit a66b10c05ee2d744189e9a2130394b070883d289 ] Yuchung Cheng and Marek Majkowski independently reported a weird behavior of TCP_USER_TIMEOUT option when used at connect() time. When the TCP_USER_TIMEOUT is reached, tcp_write_timeout() believes the flow should live, and the following condition in tcp_clamp_rto_to_user_timeout() programs one jiffie timers : remaining = icsk->icsk_user_timeout - elapsed; if (remaining <= 0) return 1; /* user timeout has passed; fire ASAP */ This silly situation ends when the max syn rtx count is reached. This patch makes sure we honor both TCP_SYNCNT and TCP_USER_TIMEOUT, avoiding these spurious SYN packets.

[ Upstream commit ba56d8ce ] Fei Liu reported a crash when doing netperf on a topo of macsec dev over veth: [ 448.919128] refcount_t: underflow; use-after-free. [ 449.090460] Call trace: [ 449.092895] refcount_sub_and_test+0xb4/0xc0 [ 449.097155] tcp_wfree+0x2c/0x150 [ 449.100460] ip_rcv+0x1d4/0x3a8 [ 449.103591] __netif_receive_skb_core+0x554/0xae0 [ 449.108282] __netif_receive_skb+0x28/0x78 [ 449.112366] netif_receive_skb_internal+0x54/0x100 [ 449.117144] napi_gro_complete+0x70/0xc0 [ 449.121054] napi_gro_flush+0x6c/0x90 [ 449.124703] napi_complete_done+0x50/0x130 [ 449.128788] gro_cell_poll+0x8c/0xa8 [ 449.132351] net_rx_action+0x16c/0x3f8 [ 449.136088] __do_softirq+0x128/0x320 The issue was caused by skb's true_size changed without its sk's sk_wmem_alloc increased in tcp/skb_gro_receive(). Later when the skb is being freed and the skb's truesize is subtracted from its sk's sk_wmem_alloc in tcp_wfree(), underflow occurs. macsec is calling gro_cells_receive() to receive a packet, which actually requires skb->sk to be NULL. However when macsec dev is over veth, it's possible the skb->sk is still set if the skb was not unshared or expanded from the peer veth. ip_rcv() is calling skb_orphan() to drop the skb's sk for tproxy, but it is too late for macsec's calling gro_cells_receive(). So fix it by dropping the skb's sk earlier on rx path of macsec. Fixes: 5491e7c6 ("macsec: enable GRO and RPS on macsec devices") Reported-by:

[ Upstream commit 3fe4b335 ] Endpoints with zero wMaxPacketSize are not usable for transferring data. Ignore such endpoints when looking for valid in, out and status pipes, to make the driver more robust against invalid and meaningless descriptors. The wMaxPacketSize of the out pipe is used as divisor. So this change fixes a divide-by-zero bug. Reported-by: syzbot+ce366e2b8296e25d84f5@syzkaller.appspotmail.com Signed-off-by:

[ Upstream commit 108639aac35eb57f1d0e8333f5fc8c7ff68df938 ] struct archdr is only big enough to hold the header of various types of arcnet packets. So to provide enough space to hold the data read from hardware provide a buffer large enough to hold a packet with maximal size. The problem was noticed by the stack protector which makes the kernel oops. Signed-off-by:

[ Upstream commit 10f966bb ] f2fs uses EFAULT as error number to indicate filesystem is corrupted all the time, but generic filesystems use EUCLEAN for such condition, we need to change to follow others. This patch adds two new macros as below to wrap more generic error code macros, and spread them in code. EFSBADCRC EBADMSG /* Bad CRC detected */ EFSCORRUPTED EUCLEAN /* Filesystem is corrupted */ Reported-by:

[ Upstream commit c5c1a030 ] In rds_bind(), an rds_sock is added to the RDS bind hash table before rs_transport is set. This means that the socket can be found by the receive code path when rs_transport is NULL. And the receive code path de-references rs_transport for congestion update check. This can cause a panic. An rds_sock should not be added to the bind hash table before all the needed fields are set. Reported-by: syzbot+4b4f8163c2e246df3c4c@syzkaller.appspotmail.com Signed-off-by:

[ Upstream commit 8b142a00 ] At least sch_red and sch_tbf don't implement ->tcf_block() while still have a non-zero tc "class". Instead of adding nop implementations to each of such qdisc's, we can just relax the check of cops->tcf_block() in tc_bind_tclass(). They don't support TC filter anyway.
