* Move code shared between libpq and backend from backend/libpq/ to common/.Heikki Linnakangas2016-09-02
| | | | | | | | | | | | | | | | | | | | | | When building libpq, ip.c and md5.c were symlinked or copied from src/backend/libpq into src/interfaces/libpq, but now that we have a directory specifically for routines that are shared between the server and client binaries, src/common/, move them there. Some routines in ip.c were only used in the backend. Keep those in src/backend/libpq, but rename to ifaddr.c to avoid confusion with the file that's now in common. Fix the comment in src/common/Makefile to reflect how libpq actually links those files. There are two more files that libpq symlinks directly from src/backend: encnames.c and wchar.c. I don't feel compelled to move those right now, though. Patch by Michael Paquier, with some changes by me. Discussion: <69938195-9c76-8523-0af8-eb718ea5b36e@iki.fi>

* Remove code to match IPv4 pg_hba.conf entries to IPv4-in-IPv6 addresses.Tom Lane2015-02-17
| | | | | | | | | | | | | | | | | | | | | | | | | In investigating yesterday's crash report from Hugo Osvaldo Barrera, I only looked back as far as commit f3aec2c7f51904e7 where the breakage occurred (which is why I thought the IPv4-in-IPv6 business was undocumented). But actually the logic dates back to commit 3c9bb8886df7d56a and was simply broken by erroneous refactoring in the later commit. A bit of archives excavation shows that we added the whole business in response to a report that some 2003-era Linux kernels would report IPv4 connections as having IPv4-in-IPv6 addresses. The fact that we've had no complaints since 9.0 seems to be sufficient confirmation that no modern kernels do that, so let's just rip it all out rather than trying to fix it. Do this in the back branches too, thus essentially deciding that our effective behavior since 9.0 is correct. If there are any platforms on which the kernel reports IPv4-in-IPv6 addresses as such, yesterday's fix would have made for a subtle and potentially security-sensitive change in the effective meaning of IPv4 pg_hba.conf entries, which does not seem like a good thing to do in minor releases. So let's let the post-9.0 behavior stand, and change the documentation to match it. In passing, I failed to resist the temptation to wordsmith the description of pg_hba.conf IPv4 and IPv6 address entries a bit. A lot of this text hasn't been touched since we were IPv4-only.

* check socket creation errors against PGINVALID_SOCKETBruce Momjian2014-04-16
| | | | | | | | Previously, in some places, socket creation errors were checked for negative values, which is not true for Windows because sockets are unsigned. This masked socket creation errors on Windows. Backpatch through 9.0. 8.4 doesn't have the infrastructure to fix this.

* On HP/UX, the structs used by ioctl(SIOCGLIFCONF) are named differentlyHeikki Linnakangas2011-04-13
| | | | | | | | than on other platforms, and only IPv6 addresses are returned. Because of those two issues, fall back to ioctl(SIOCGIFCONF) on HP/UX, so that it at least compiles and finds IPv4 addresses. This function is currently only used for interpreting samehost/samenet in pg_hba.conf, which isn't that critical.

* Create typedef pgsocket for storing socket descriptors.Magnus Hagander2010-01-10
| | | | | | | | This silences some warnings on Win64. Not using the proper SOCKET datatype was actually wrong on Win32 as well, but didn't cause any warnings there. Also create define PGINVALID_SOCKET to indicate an invalid/non-existing socket, instead of using a hardcoded -1 value.

(Turns out this is reversing a bad decision from some years ago...) Fix up references to crypt.h as needed. I looked into moving the code into src/port, but the headers in src/include/libpq are sufficiently intertwined that it seems more work than it's worth to do that.

I was not aware that we > had any breakage there. patch-tmp-schema.txt contains the following bits: *) Changes pg_namespace_aclmask() so that the superuser is always able to create objects in the temp namespace. *) Changes pg_namespace_aclmask() so that if this is a temp namespace, objects are only allowed to be created in the temp namespace if the user has TEMP privs on the database. This encompasses all object creation, not just TEMP tables. *) InitTempTableNamespace() checks to see if the current user, not the session user, has access to create a temp namespace. The first two changes are necessary to support the third change. Now it's possible to revoke all temp table privs from non-super users and limiting all creation of temp tables/schemas via a function that's executed with elevated privs (security definer). Before this change, it was not possible to have a setuid function to create a temp table/schema if the session user had no TEMP privs. patch-area-path.txt contains: *) Can now determine the area of a closed path. patch-dfmgr.txt contains: *) Small tweak to add the library path that's being expanded. I was using $lib/foo.so and couldn't easily figure out what the error message, "invalid macro name in dynamic library path" meant without looking through the source code. With the path in there, at least I know where to start looking in my config file. Sean Chittenden
