-This quarter, Ludovic Courtès contributed a [continuously-built Nix-based QEMU
-image](http://lists.gnu.org/archive/html/bug-hurd/2011-11/msg00042.html),
-raising the count of GNU/Hurd distributions to three: [[Debian
-GNU/Hurd|hurd/running/debian]], [[hurd/running/Arch_Hurd]], and now
-[[hurd/running/NixOS]].  His build is still pretty basic, but a step into the
-right direction: [[!wikipedia "continuous integration"]] is a great feature for
-automated testing.
-
-Samuel Thibault followed suit with a [new Debian GNU/Hurd disk
-set](http://lists.debian.org/debian-hurd/2011/12/msg00095.html) as a christmas
-gift, and
-[identified](http://lists.debian.org/debian-hurd/2011/11/msg00095.html) three
-easy porting cases with solutions:
-
-  * undefined reference to `dl_*`: add `-ldl` for building
-  * undefined reference to `main`: missing `gnu*` case in the linking part of
-    `configure.ac` or `.in`
-  * undefined reference to `clock_gettime` or `crypt`: add `-lrt` or `-lcrypt`
-
-These should help all those who want to help [[porting_packages|hurd/porting]].

-Maksym Planeta and Richard Braun [finished
-integration](http://lists.gnu.org/archive/html/bug-hurd/2011-12/msg00046.html)
-of the slab allocator.  From [[IRC]], freenode, #hurd, 2011-11-14:
-
-    <braunr> there shouldn't be any noticeable difference [...]
-    <braunr> a bit less fragmentation  
-    <braunr> more memory can be reclaimed by the VM system  
-    <braunr> there are debugging features  
-    <braunr> it's SMP ready  
-    <braunr> and overall cleaner than the zone allocator  
-    <braunr> although a bit slower on the free path (because of
-      what's performed to reduce fragmentation)  
-    <braunr> but even "slower" here is completely negligible
-
-This also

-our first [[FOSS Factory|donate#FOSS_Factory]] project -- one [[tag/bounty]]
-has been redeemed, more are waiting.
-
-Sergio Lopez documented his work on
-[[better_memory_management_and_memfs|Sergio_Lopez]], making it easier for other
-hackers to join in working on that topic.

+
+There are two implementations of `mmap` for GNU Hurd:
+`sysdeps/mach/hurd/mmap.c` (main implementation) and
+`sysdeps/mach/hurd/dl-sysdep.c` (*Minimal mmap implementation sufficient for
+initial loading of shared libraries.*).
+
+  * `MAP_COPY`
+
+    What exactly is that?  `elf/dl-load.c` has some explanation.
+    <http://lkml.indiana.edu/hypermail/linux/kernel/0110.1/1506.html>
+
+    It is only handled in `dl-sysdep.c`, when `flags & (MAP_COPY|MAP_PRIVATE)`
+    is used for `vm_map`'s `copy` parameter, and `mmap.c` uses `! (flags &
+    MAP_SHARED)` instead, which seems inconsistent?
+
+
+# `io_map` Failure
+
+This is the [[libnetfs: `io_map`|open_issues/libnetfs_io_map]] issue.
+
+[[!tag open_issue_glibc]]
+
+Review of `mmap` usage in generic bits of glibc, based on
+a1bcbd4035ac2483dc10da150d4db46f3e1744f8 (2012-03-11), listing these cases
+where failure (due to `io_map` failing; that is, invocations where a `fd` is
+passed) is not properly handled.
+
+`catgets/open_catalog.c`, `iconv/gconv_cache.c`, `intl/loadmsgcat.c`,
+`locale/loadlocale.c` have fallback code for the `MAP_FAILED` case.
+
+[[tschwinge]]'s current plan is to make the following cases do the same (if
+that is possible); probably by introducing a generic `mmap_or_read` function,
+that first tries `mmap` (and that will succeed on Linux-based systems and also
+on Hurd-based, if it's backed by [[hurd/libdiskfs]]), and if that fails tries
+`mmap` on anonymous memory and then fills it by `read`ing the required data.
+This is also what the [[hurd/exec]] server is doing (and is the reason that the
+`./true` invocation on [[libnetfs: `io_map`|open_issues/libnetfs_io_map]]
+works, to my understanding): see `exec.c:prepare`, if `io_map` fails,
+`e->filemap == MACH_PORT_NULL`; then `exec.c:map` (as invoked from
+`exec.c:load_section`, `exec.c:check_elf`, `exec.c:do_exec`, or
+`hashexec.c:check_hashbang`) will use `io_read` instead.
+
+Doing so potentially means reading in a lot of unused data -- but we probably
+can't do any better?
+
+In parallel (or even alternatively?), it should be researched how Linux (or any
+other kernel) implements `mmap` on NFS and similar file systems, and then
+implement the same in [[hurd/libnetfs]] and/or [[hurd/translator/nfs]], etc.
+
+Here, also probably the whole mapping region [has to be
+read](http://lists.gnu.org/archive/html/bug-hurd/2001-10/msg00306.html) at
+`mmap` time.
+
+List of files without fallback code for the *`MAP_FAILED` due to `io_map`
+failed* case:
+
+  * `elf/cache.c`
+
+  * `elf/dl-load.c`
+

+This quarter, Ludovic Courtès contributed a [continuously-built Nix-based QEMU
+image](http://lists.gnu.org/archive/html/bug-hurd/2011-11/msg00042.html),
+raising the count of GNU/Hurd distributions to three: [[Debian
+GNU/Hurd|hurd/running/debian]], [[hurd/running/Arch_Hurd]], and now
+[[hurd/running/Nix]].  His build is still pretty basic, but a step into the
+right direction: [[!wikipedia "continuous integration"]] is a great facility
+for automated testing.
+
+Samuel Thibault followed suit with a [new Debian GNU/Hurd disk
+set](http://lists.debian.org/debian-hurd/2011/12/msg00095.html) as a christmas
+gift, and
+[identified](http://lists.debian.org/debian-hurd/2011/11/msg00095.html) three
+easy porting cases with solutions:
+
+  * undefined reference to `dl_*`: add `-ldl` for building
+  * undefined reference to `main`: missing `gnu*` case in the linking part of
+    `configure.ac` or `.in`
+  * undefined reference to `clock_gettime` or `crypt`: add `-lrt` or `-lcrypt`
+
+These should help all those who want to help [[porting_packages|hurd/porting]].

+of the slab allocator.  From [[IRC]], freenode, #hurd, 2011-11-14:
+
+    <braunr> there shouldn't be any noticeable difference [...]
+    <braunr> a bit less fragmentation  
+    <braunr> more memory can be reclaimed by the VM system  
+    <braunr> there are debugging features  
+    <braunr> it's SMP ready  
+    <braunr> and overall cleaner than the zone allocator  
+    <braunr> although a bit slower on the free path (because of

+    <braunr> but even "slower" here is completely negligible

+
+The **GNU Hurd** is the GNU project's replacement for the Unix kernel.  It is a
+collection of servers that run on the Mach microkernel to implement file
+systems, network protocols, file access control, and other features that are
+implemented by the Unix kernel or similar kernels (such as Linux).  [[More
+detailed|hurd/documentation]].
+
+**GNU Mach** is the microkernel upon which a GNU Hurd system is based.  It
+provides an Inter Process Communication (IPC) mechanism that the Hurd uses to
+define interfaces for implementing in a distributed multi-server fashion the
+services a traditional operating system kernel provides.  [[More
+detailed|microkernel/mach/gnumach]].
