[PATCH v4 2/4] QIOChannelSocket: Fix zero-copy send so socket flush works

Somewhere between v6 and v7 the of the zero-copy-send patchset a crucial part of the flushing mechanism got missing: incrementing zero_copy_queued. Without that, the flushing interface becomes a no-op, and there is no guarantee the buffer is really sent. This can go as bad as causing a corruption

Patches 1 & 2 are about a fix needed to make zero-copy flush work. The code that incremented the sendmsg counter ended up missing in the last versions of the patchset, causing the flush to never happen. Patch 3 is about an improvement on flushing that improves sending performance. Patch 4 is abo

[PATCH v4 3/4] migration: zero-copy flush only at the end of bitmap scanning

When sending memory pages with MSG_ZEROCOPY, it's necessary to flush to make sure all dirty pages are sent before a future version of them happens to be sent. Currently, the flush happens every time at the end of ram_save_iterate(), which usually happens around 20x per second, due to a timeout. C
