Sv: Problems with native Unix domain sockets on Win 10/2019
Hi all Does anyone know the status of these fixes ? I saw an announcement for cygwin-3.2.0-0.1 that seemed to contain some AF_UNIX-related fixes but I fail to find out where that distribution exists (if it is supposed to be publicly accessible?), but I tried out the 2021-03-01 snapshot and perhaps they are similar ? We bumped into some AF_UNIX-related issues when trying the 2021-03-01 -snapshot though. It might be some flaws in our code base but the same code works in quite a few Linux-distros We're more than willing to help out with testing this and/or trying to narrow down any possible cygwin issues, but first we'd be glad if someone could give us some kind of status report of this (so no one is doing any unnecessary work) Best regards, Kristian p.s. I tried to build the topic/af_unix -branch according to the FAQ, but there was some issues d.s. > > Hi Ken, Corinna > > > > Sorry for the delay in responding.

I think you can download pre-released builds from: https://cygwin.com/snapshots/ As mentioned already, the fix here is not actually support of AF_UNIX sockets natively. My understanding is that they are implemented over loopback TCP in cygwin, but the fix allows native AF_UNIX sockets to be handled (eg deleted) as regular files through regular cygwin commands.

Thank you very much for looking into it. When do you think it would be available in a form that regular users would be able to update/install? Corinna decides when to make a new Cygwin release. My best guess is "pretty soon". Also, one observation FYI, is that the "ls -l" command on Unix normally indicates sockets with an "s" as the first character of the output: eg srwxr-xr-x 1 Michael None 0 Feb 7 11:19 foo.sock Currently, what is shown on Cygwin is -rwxr-xr-x 1 Michael None 0 Feb 7 11:19 foo.sock indicating a regular file. Right. From Cygwin's point of view, it is a regular file. There might come a time when Cygwin's AF_UNIX implementation makes use of native Windows AF_UNIX sockets on systems that support them. But that time is not currently in sight.

Re: Different symlink resolution in native console vs. terminal
On 2021/03/10 14:51, Andrey Repin wrote: Running `pwd -P` or `readlink -e .` in a specific directory from native terminal provide unresolved answers. The directory $HOME/Documents/EVE is a symlink pointing to $HOME\Documents\Games\EVE. When running either command inside the directory from native terminal, the result is literally /home/Documents/EVE, but when running the same command from mintty inside same directory, the results may vary. $HOME/Documents/EVE or $HOME/Documents/Games/EVE (which is expected answer). It also seems, there are results difference between `bash -l` `and bash -i` and `pwd -P` and `readlink -e .`. Generally, "pwd" is more correct. 1) When you look at the processes(native v mintty), are both the same #bits? 2) Can you reproduce this with any other dir? Both Documents and Games have multiple copies due to the public docs+games are in the docs+games library (along with user versions). Maybe the winterm is picking up a different file? 3) do you actually have a directory named '$HOME' or is it a real dirname? 4) the symlink is in 'EVE' in both cases, yes? Can you copy 'EVE' (the symlink) to a dir like /tmp and do they resolve differently there? I think one or both of those dirs have a GUID associated with them, maybe one is using a different GUID than the other? I also have Win7x64 but have never seen them misbehaving...

You can install cygwin-3.2.0-0.1 in the usual way, through Cygwin's setup program. Since it's a test release, you'll have to explicitly select that release; setup won't just offer it to you.

I tried to build the topic/af_unix -branch according to the FAQ, but there was some issues I'm still in the middle of some things on that branch, and I haven't had much time to work on it recently. I hope to get back to it very soon. In order to build it, you need to add -D__WITH_AF_UNIX to CXXFLAGS. In order to test it, you need #undef AF_UNIX #define AF_UNIX 31 after including Ken -- Problem reports: https://cygwin.com/problems.html FAQ: https://cygwin.com/faq/ Documentation:https://cygwin.com/docs.html Unsubscribe info: https://cygwin.com/ml/#unsubscribe-simple
[ANNOUNCEMENT] [SECURITY] stunnel 5.58-1
stunnel 5.58-1 is now available in Cygwin. This release includes one security fix related to Cygwin: * The "redirect" option was fixed to properly handle unauthenticated requests (thx to Martin Stein). Plus other new features and bug fixes. Everyone should upgrade to this release. Please see the upstream changelog[1] for the full list. stunnel is a program that allows you to encrypt arbitrary TCP connections inside TLS (Transport Layer Security, the successor to Secure Sockets Layer (SSL)). stunnel can allow you to secure non-TLS-aware daemons and protocols (like POP, IMAP, LDAP, etc) by having stunnel provide the encryption, requiring no changes to the daemon's code.
