I noticed something strange when cop= ying files to a Linux box using scp recently (I'm using 14-main GENERIC-NODEBUG)= and the problems recently disappeared. Did you check the Linux tcp commits recently? For example this one: commit 686dc2db2a0fdc1d34b424ec2c0a735becd8d62b Author: Neal Cardwell Date: Sat Sep 3 08:10:23 2022 -0400 tcp: fix early ETIMEDOUT after spurious non-SACK RTO Fix a bug reported and analyzed by Nagaraj Arankal, where the handling of a spurious non-SACK RTO could cause a connection to fail to clear retrans_stamp, causing a later RTO to very prematurely time out the connection with ETIMEDOUT. Here is the buggy scenario, expanding upon Nagaraj Arankal's excellent report: https://github.com/LineageOS/android_kernel_xiaomi_onclite/commit/be8176c25= c32607cf357317880038a1e4a935bd7 --HPS --=20 You are receiving this mail because: You are the assignee for the bug.=
