Subject: tests/tcg/linux-test: Fix random hangs in test_socket
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=b9e6074fc5b429b1e956e9c60db7e284a91e0f3d;p=qemu.git

tests/tcg/linux-test: Fix random hangs in test_socket

test_socket hangs randomly in connect(), especially when run without
qemu. Apparently the reason is that linux started treating backlog
value of 0 literally instead of rounding it up since v4.4 (commit
ef547f2ac16b).

So set it to 1 instead.
