2007-10-18kbuild: modpost problem when symbols move from one module to anotherTrent Piepho1-0/+3
When part of build an external module tree, modpost first reads in the kernel's and then the external tree's Module.symvers files. From these files it establishes a symbol => module mapping. When it later reads in each module built and processes the symbols it finds, it discovers the symbol=>module mapping from Module.symvers and leaves it as it is. The problem comes with a module has been re-named or a symbol has moved from one module to another, since the Module.symvers file was generated. modpost does not update the symbol=>module mapping when it finds the new location of the symbol when scanning the newly built modules. This results in the module containing incorrect dependency information and the new Module.symvers file written by modpost will also contain the incorrect mappings, perpetuating the problem to the next build, and so on. When building the out of kernel development tree for kernel subsystem, like v4l-dvb or ALSA, deleting the external Module.symvers file before building (which the kernel build system doesn't do and shouldn't be necessary anyway), won't fix the problem. modpost still reads the kernel's Module.symvers, and since we a building a kernel subsystem, it will define the same symbols as the external modules.

2007-10-18kbuild: mailing list has movedSam Ravnborg1-1/+2
The old list at sourceforge had a few issues: - it was subscriber-only - it were relying on moderation And I could see several mails did not get to the list lately so I decided this was a good time for a new list. I already requested marc.info to archieve the new list - and I dunno where else the old list was archieved but we ought to update. I have no access to the list of subscribers on the old list so people will have to subscribe manually. How to subscribe: send a mail to: majordomo@vger.kernel.org containing following text: subscribe linux-kbuild See also http://vger.kernel.org/vger-lists.html Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
2007-10-18kbuild: check asm symlink when building a kernelSam Ravnborg1-8/+18
We often hit the situation where the asm symlink in include/ points to the wrong architecture. In 9 out of 10 cases thats because we forgot to set ARCH but sometimes we just reused the same tree for another ARCH. For the merged x86 tree we need to create a new symlink but this is not obvious. So with the following patch we check if the symlink points to the correct architecture and error out if this is not the case. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>

2007-10-179p: soften invalidation in loose_modeEric Van Hensbergen1-2/+4
Loose mode in 9p utilizes the page cache without respecting coherency with the server. Any writes previously invaldiated the entire mapping for a file. This patch softens the behavior to only invalidate the region of the actual write. Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>
2007-10-179p: attach-per-userLatchesar Ionkov9-72/+247
The 9P2000 protocol requires the authentication and permission checks to be done in the file server. For that reason every user that accesses the file server tree has to authenticate and attach to the server separately. Multiple users can share the same connection to the server. Currently v9fs does a single attach and executes all I/O operations as a single user. This makes using v9fs in multiuser environment unsafe as it depends on the client doing the permission checking. This patch improves the 9P2000 support by allowing every user to attach separately. The patch defines three modes of access (new mount option 'access'): - attach-per-user (access=user) (default mode for 9P2000.u) If a user tries to access a file served by v9fs for the first time, v9fs sends an attach command to the server (Tattach) specifying the user. If the attach succeeds, the user can access the v9fs tree. As there is no uname->uid (string->integer) mapping yet, this mode works only with the 9P2000.u dialect. - allow only one user to access the tree (access=<uid>) Only the user with uid can access the v9fs tree. Other users that attempt to access it will get EPERM error. - do all operations as a single user (access=any) (default for 9P2000) V9fs does a single attach and all operations are done as a single user. If this mode is selected, the v9fs behavior is identical with the current one. Signed-off-by: Latchesar Ionkov <lucho@ionkov.net> Signed-off-by: Eric Van Hensbergen <ericvh@gmail.com>

2007-10-17x86: vdso linker script cleanupRoland McGrath1-7/+9
I can't see the reason ". = VDSO_PRELINK + 0x900;" was ever there in the linker script for the x86_64 vDSO. I can't find anything that depends on this magic offset, or that should care at all about the particular location of of the .data section (all from vvar.c) in the vDSO image. If it is really desireable to place .data at 0x900, then it should be after all the other sections so they fill in the space up to 0x900. This removes the 0x900 magic and cleans up the output sections generally in the vDSO linker script. This saves a few hundred bytes in the size of the vDSO file, bringing it back well under 4kb total so that its vma only needs one page.
