[libvirt] [PATCH] rpc: remove trailing carriage return character in error string

If the error message string ends with '\r\n', it is not enough to remove '\n' only which leads to messed string. Example, after three time incorrect password input, virsh command virsh -c qemu://remoteserver/system will report error like: : Connection reset by peerey,gssapi-keyex,gssapi-with-mic,password). it should be: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password). : Connection reset by peer The terminal interprets '\r' as "move the cursor back to the start of the current line", so we have to remove the character if it exists. --- src/rpc/virnetsocket.c | 8 +++++++- 1 files changed, 7 insertions(+), 1 deletions(-) diff --git a/src/rpc/virnetsocket.c b/src/rpc/virnetsocket.c index 08dfbb0..8385d88 100644 --- a/src/rpc/virnetsocket.c +++ b/src/rpc/virnetsocket.c @@ -985,8 +985,14 @@ reread: virFileReadLimFD(sock->errfd, 1024, &errout) >= 0 && errout != NULL) { size_t elen = strlen(errout); - if (elen && errout[elen-1] == '\n') + if (elen && errout[elen-1] == '\n') { errout[elen-1] = '\0'; + + /* remove trailing '\r' if it exists */ + if (elen-1 && errout[elen-2] == '\r') { + errout[elen-2] = '\0'; + } + } } if (ret < 0) { -- 1.7.7.5
