Hi ML-followers,
I occasionally observe stalled scp connections while copying logfile archives from a debian server to cygwin on Windows 7. Besides https://sourceware.org/ml/cygwin/2015-02/msg00575.html I did not find similar issues, but there is no blocking/non-blocking switch involved in the middle of the data transmission (at random places in subsequent tests) through the pipe, where some data is lost (pls see below).
Pls find the redacted output of my "cygcheck -svr" attached. I also noticed that issue also before upgrading my cygwin to that latest version.
As I'm not into the details of read/write functions, I was only able to track down the issue as follows - I hope it is reproducible or otherwise helpful - so now I need your help:
1) I added some instrumentation in scp/ssh (both binaries copied to /usr/local/bin/ and used below):
user@host /usr/src/openssh-6.8p1-1.src/openssh-6.8p1-debug
$ grep -n -C4 TK: *.c
channels.c-1724-
channels.c-1725- if (c->datagram) {
channels.c-1726- /* ignore truncated writes, datagrams might get lost */
channels.c-1727- len = write(c->wfd, buf, dlen);
channels.c:1728:logit("TK: channels.c: channel_handle_wfd(1): write: len=%d, buf=%.16s", len, buf);
channels.c-1729- free(data);
channels.c-1730- if (len < 0 && (errno == EINTR || errno == EAGAIN ||
channels.c-1731- errno == EWOULDBLOCK))
channels.c-1732- return 1;
--
channels.c-1745- dlen = MIN(dlen, 8*1024);
channels.c-1746-#endif
channels.c-1747-

channels.c:1749:logit("TK: channels.c: channel_handle_wfd(2): write: len=%d, buf=%.16s", len, buf);
channels.c-1750- if (len < 0 &&
channels.c-1751- (errno == EINTR || errno == EAGAIN || errno == EWOULDBLOCK))
channels.c-1752- return 1;

channels.c:2372:logit("TK: channels.c: channel_input_data: data_len=%d, buf=%.16s", data_len, data);
channels.c-2373- win_len = data_len;
channels.c-2374- if (c->datagram)
channels.c-2375- win_len += 4; /* string length header */
channels.c-2376-

dispatch.c-112- if (type > 0 && type < DISPATCH_MAX &&
dispatch.c-113- ssh->dispatch[type] != NULL) {
dispatch.c-114- if (ssh->dispatch_skip_packets) {
dispatch.c-115- debug2("skipped packet (type %u)", type);
--
scp.c-1110- count += amt;
scp.c-1111- do {
scp.c-1112- j = atomicio6(read, remin, cp, amt,
scp.c-1113- scpio, &statbytes);
scp.c:1114:logit("TK: scp.c: sink: amt=%d, j=%d, i=%d, size=%d, count=%d, buf=%.16s", amt, j, i, size, count, cp);
scp.c-1115- if (j == 0) {
scp.c-1116- run_err("%s", j != EPIPE ?
scp.c-1117- strerror(errno) :
scp.c-1118- "dropped connection");
2) Generated easily debuggable (numbered 16k ascii blocks) HUGEFILE on a debian server (file size taken from an original log archive):
$ for BLOCK in `seq -w 1 1 94795`; do for ELEM in `seq -w 1 1 1024`; do echo -n "B0$BLOCK-N00$ELEM-"; done; done > TEST.txt
3) Pulled that file in a loop from the debian server to the local cygwin on Windows 7:
$ while true; do /usr/local/bin/scp -v -C -o BatchMode=yes user@10.IP2.IP3.IP4:logDownload_m/TEST.txt 93_KO_TEST.txt 2>&1 | tee 93_KO_scp_trace.txt; echo; date; echo; sleep 15; done
4) In case of stalled scp (in my env, it does not take that much time to get it, maybe 10-to-30 tries), collect and compare the "KO" output to a previously recorded and prepared "OK" output:
$ split -b 163840 -a 5 93_KO_TEST.txt 93_KO_TEST.txt.split_
$ for FILE in 93_OK_TEST.txt.split_*; do echo "$FILE"; diff -q $FILE `echo $FILE | sed -re "s/93_OK_/93_KO_/g"` || break; done
. . .
93_OK_TEST.txt.split_aanqv
93_OK_TEST.txt.split_aanqw
Files 93_OK_TEST.txt.split_aanqw and 93_KO_TEST.txt.split_aanqw differ
$ sdiff <(cat 93_OK_TEST.txt.split_aanqw | sed -re "s/(B......-N001024-)/\1\n/g") <(cat 93_KO_TEST.txt.split_aanqw | sed -re "s/(B......-N001024-)/\1\n/g")

... So, the 16k block "B092267" is missing in the "KO" case, lets check the scp/ssh logs, where we do have 3 steps where the HUGEFILE data is handled:
a) Writing it to the channel buffer in the ssh process after reading it from the socket and after decryption and decompression: "TK: channels.c: channel_input_data:"
b) Reading it from the channel buffer and writing it to the pipe towards the scp parent process in ssh process: "TK: channels.c: channel_handle_wfd(2):"
c) Reading it from the pipe in the scp process to write it to the target file: "TK: scp.c: sink:"
The logs show that the buffer is handled in a) and b), but does not show up in c), it is simply lost...
$ for TRACKER in TK:.channels.c:.channel_input_data: TK:.channels.c:.channel_handle_wfd.2.: TK:.scp.c:.sink:; do echo; cat 93_KO_scp_trace.txt | grep "$TRACKER" | grep "B0922[67]"; done

The 3rd line of c) "TK: scp.c: sink:" should be "buf=B092269-N000001-" if all of the 64k data of the 2nd line "count=65536, buf=B092265-N000001-" would have been read correctly from the pipe, but it is: "buf=B092270-N000001-", i.e. one 16k block is written to the pipe by ssh ("TK: channels.c: channel_handle_wfd(2): write: len=16384, buf=B092267-N000001-"), but does not show up on teh other end of the pipe in scp.
In case bigger blocks are written to the pipe by ssh (e.g. "len=32768"), the bigger blocks get lost and does not show up in scp, e.g.:

Hi Theodor,
Question: last cygwin 2.0.4 or previous version ?
Maybe is no relevant for your case but there were some fixes
In theory during tests a 64K buffer should be faster

I have no good idea how to debug this further, other than running under
strace (which takes a lot of patience), but I tried to do the same with
the stock scp 6.8 on Cygwin 2.0.2 x86_, basically a loop:
while true
do
scp -C my_linux_box:TEST.txt . && diff TEST.orig TEST.txt || break
done
The TEST.orig/TEST.txt file was generated as described in your OP. The
loop is running now for a couple of hours without fail.
Any chance this is BLODA-induced?

unfortunately, my issue seems to be not interesting enough to trigger someones attention... ;)
Was my issue well described or do you have further questions? I'd appreciate any help leading me forward, e.g. maybe some hints in howto instrument cygwin sources to be able to further trace the data through and debug into the cygwins write / read functions...
Thanks,
Theo

Betreff: cygwin on W7: stalled scp (openssh-6.8p1), lost ssh-scp-pipe data
Hi ML-followers,
I occasionally observe stalled scp connections while copying logfile archives from a debian server to cygwin on Windows 7. Besides https://sourceware.org/ml/cygwin/2015-02/msg00575.html I did not find similar issues, but there is no blocking/non-blocking switch involved in the middle of the data transmission (at random places in subsequent tests) through the pipe, where some data is lost (pls see below).
Pls find the redacted output of my "cygcheck -svr" attached. I also noticed that issue also before upgrading my cygwin to that latest version.
As I'm not into the details of read/write functions, I was only able to track down the issue as follows - I hope it is reproducible or otherwise helpful - so now I need your help:
1) I added some instrumentation in scp/ssh (both binaries copied to /usr/local/bin/ and used below):
user@host /usr/src/openssh-6.8p1-1.src/openssh-6.8p1-debug
$ grep -n -C4 TK: *.c

channels.c-1726- /* ignore truncated writes, datagrams might get lost */

channels.c:1728:logit("TK: channels.c: channel_handle_wfd(1): write: len=%d, buf=%.16s", len, buf);
channels.c-1729- free(data);

scp.c-1115- if (j == 0) {
scp.c-1116- run_err("%s", j != EPIPE ?
scp.c-1117- strerror(errno) :

2) Generated easily debuggable (numbered 16k ascii blocks) HUGEFILE on a debian server (file size taken from an original log archive):
$ for BLOCK in `seq -w 1 1 94795`; do for ELEM in `seq -w 1 1 1024`; do echo -n "B0$BLOCK-N00$ELEM-"; done; done > TEST.txt
3) Pulled that file in a loop from the debian server to the local cygwin on Windows 7:
$ while true; do /usr/local/bin/scp -v -C -o BatchMode=yes user@10.IP2.IP3.IP4:logDownload_m/TEST.txt 93_KO_TEST.txt 2>&1 | tee 93_KO_scp_trace.txt; echo; date; echo; sleep 15; done
4) In case of stalled scp (in my env, it does not take that much time to get it, maybe 10-to-30 tries), collect and compare the "KO" output to a previously recorded and prepared "OK" output:
$ split -b 163840 -a 5 93_KO_TEST.txt 93_KO_TEST.txt.split_
$ for FILE in 93_OK_TEST.txt.split_*; do echo "$FILE"; diff -q $FILE `echo $FILE | sed -re "s/93_OK_/93_KO_/g"` || break; done
. . .
93_OK_TEST.txt.split_aanqv
93_OK_TEST.txt.split_aanqw
Files 93_OK_TEST.txt.split_aanqw and 93_KO_TEST.txt.split_aanqw differ
$ sdiff <(cat 93_OK_TEST.txt.split_aanqw | sed -re "s/(B......-N001024-)/\1\n/g") <(cat 93_KO_TEST.txt.split_aanqw | sed -re "s/(B......-N001024-)/\1\n/g")

... So, the 16k block "B092267" is missing in the "KO" case, lets check the scp/ssh logs, where we do have 3 steps where the HUGEFILE data is handled:
a) Writing it to the channel buffer in the ssh process after reading it from the socket and after decryption and decompression: "TK: channels.c: channel_input_data:"
b) Reading it from the channel buffer and writing it to the pipe towards the scp parent process in ssh process: "TK: channels.c: channel_handle_wfd(2):"
c) Reading it from the pipe in the scp process to write it to the target file: "TK: scp.c: sink:"
The logs show that the buffer is handled in a) and b), but does not show up in c), it is simply lost...
$ for TRACKER in TK:.channels.c:.channel_input_data: TK:.channels.c:.channel_handle_wfd.2.: TK:.scp.c:.sink:; do echo; cat 93_KO_scp_trace.txt | grep "$TRACKER" | grep "B0922[67]"; done

The 3rd line of c) "TK: scp.c: sink:" should be "buf=B092269-N000001-" if all of the 64k data of the 2nd line "count=65536, buf=B092265-N000001-" would have been read correctly from the pipe, but it is: "buf=B092270-N000001-", i.e. one 16k block is written to the pipe by ssh ("TK: channels.c: channel_handle_wfd(2): write: len=16384, buf=B092267-N000001-"), but does not show up on teh other end of the pipe in scp.
In case bigger blocks are written to the pipe by ssh (e.g. "len=32768"), the bigger blocks get lost and does not show up in scp, e.g.:
