[PATCH v8 0/7] Fix sock_send reordering issue (#52401)
by Jinoh Kang 25 Mar '22

25 Mar '22

This fixes the send part of the issue #52401 [1]: "Improper synchronization in sock_recv/sock_send leads to arbitrary reordering of completion of I/O requests", which was initially reported (outside Bugzilla) by Dongwan Kim [2]. Changelog: v1 -> v2: - drop patch "server: Compact struct set_async_direct_result_reply." - add async and fd arguments to async_initial_status_callback - recv_socket_initial_callback: pass OOB flag via private instead of implementing two separate functions for OOB and non-OOB - detect short write in send_socket_initial_callback - preserve the behaviour of returning success if we had a short write and the socket is nonblocking and force_async is unset v2 -> v3: - fix typo in comment v3 -> v4: - fix typo in commit message - address feedback - drop patch "server: Defer postprocessing until after setting initial status in recv_socket handler." v4 -> v5: - drop patch "server: Add async_initial_status_callback." - drop patch "server: Defer postprocessing until after setting initial status in send_socket handler." - add patch "server: Ensure completion_callback is called before async is destroyed." - add patch "ws2_32/tests: Continue sending remaining data on short write in test_write_events." - add patch "server: Defer clearing events until async is either pending or completed in send_socket handler." - add patch "server: Ensure datagram sockets are bound in send_socket." v5 -> v6: - centralise status code computation in one place, even for bind errno translation - fix erroneous subject (s/either pending or completed/completed/) v6 -> v7: - drop patch "server: Ensure completion_callback is called before async is destroyed." - add patch "server: Ensure async completion callback is called on synchronous failure." - add patch "server: Allow async completion callback to retrieve status on synchronous failure." v7 -> v8: - drop committed patches - edit commit message of "server: Ensure completion_callback is called before async is destroyed." as per feedback (thanks zf) - move a sock_reselect() into the prior if block (thanks zf) Supersedes 227636 - 227644. Supersedes 228988 - 228998. Supersedes 230282 - 230293 (sans already committed patches).

[PATCH 0/3] Implementing filename completion in cmd
by Eric Pouech 25 Mar '22

25 Mar '22

The following series implements filename completion in cmd, à la Windows (tab (resp. shift-tab) rotates in alphabetical order (resp. backwards alpha order) the available filenames starting with a given prefix). It requires two fixes in programs/conhost. Notes to Jacek - for the second patch, I tried to pick most of the APIs requiring cursor positionning. I wonder if SetConsoleCursorPosition (when y is outside a given interval) shouldn't be part of it (no concrete example at sight, just wild thinking) (something like deltay < -5 || deltay > 0) (This can be done later on anyway) Signed-off-by: Eric Pouech <eric.pouech(a)gmail.com> --- Eric Pouech (3): programs/conhost: correctly recompute start of edit line on ReadConsole programs/conhost: support relative cursor positionning programs/cmd: implement filename completion programs/cmd/batch.c | 279 ++++++++++++++++++++++++++++++++++++- programs/conhost/conhost.c | 22 ++- programs/conhost/conhost.h | 1 + 3 files changed, 294 insertions(+), 8 deletions(-)
