Eric Dumazet 4a269818a7 tcp: fix tcp_unlink_write_queue() ... Yury reported crash with this signature : [ 554.034021] [<ffff80003ccd5a58>] 0xffff80003ccd5a58 [ 554.034156] [<ffff00000888fd34>] skb_release_all+0x14/0x30 [ 554.034288] [<ffff00000888fd64>] __kfree_skb+0x14/0x28 [ 554.034409] [<ffff0000088ece6c>] tcp_sendmsg_locked+0x4dc/0xcc8 [ 554.034541] [<ffff0000088ed68c>] tcp_sendmsg+0x34/0x58 [ 554.034659] [<ffff000008919fd4>] inet_sendmsg+0x2c/0xf8 [ 554.034783] [<ffff0000088842e8>] sock_sendmsg+0x18/0x30 [ 554.034928] [<ffff0000088861fc>] SyS_sendto+0x84/0xf8 Problem is that skb->destructor contains garbage, and this is because I accidentally removed tcp_skb_tsorted_anchor_cleanup() from tcp_unlink_write_queue() This would trigger with a write(fd, <invalid_memory>, len) attempt, and we will add to packetdrill this capability to avoid future regressions.
