| * IB/cma: Add configfs for rdma_cmMatan Barak2015-12-231-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Users would like to control the behaviour of rdma_cm. For example, old applications which don't set the required RoCE gid type could be executed on RoCE V2 network types. In order to support this configuration, we implement a configfs for rdma_cm. In order to use the configfs, one needs to mount it and mkdir <IB device name> inside rdma_cm directory. The patch adds support for a single configuration file, default_roce_mode. The mode can either be "IB/RoCE v1" or "RoCE v2". Signed-off-by: Matan Barak <matanb@mellanox.com> Signed-off-by: Doug Ledford <dledford@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | This patch set adds attributes of net device and gid type to each GID in the GID table. Users that use verbs directly need to specify the GID index. Since the same GID could have different types or associated net devices, users should have the ability to query the associated GID attributes. Adding these attributes to sysfs.

A typical process filling 4000 pipes with 1 MB of data will use 4 GB of memory. On small systems it may be tricky to set the pipe max size to prevent this from happening. This patch makes it possible to enforce a per-user soft limit above which new pipes will be limited to a single page, effectively limiting them to 4 kB each, as well as a hard limit above which no new pipes may be created for this user. This has the effect of protecting the system against memory abuse without hurting other users, and still allowing pipes to work correctly though with less data at once. The limit are controlled by two new sysctls : pipe-user-pages-soft, and pipe-user-pages-hard. Both may be disabled by setting them to zero. The default soft limit allows the default number of FDs per process (1024) to create pipes of the default size (64kB), thus reaching a limit of 64MB before starting to create only smaller pipes. With 256 processes limited to 1024 FDs each, this results in 1024*64kB + (256*1024 - 1024) * 4kB = 1084 MB of memory allocated for a user. The hard limit is disabled by default to avoid breaking existing applications that make intensive use of pipes (eg: for splicing).

Compiler inserts code that perform certain kinds of checks before operations that could cause UB. If check fails (i.e. UB detected) __ubsan_handle_* function called to print error message. So the most of the work is done by compiler. This patch just implements ubsan handlers printing errors. GCC has this capability since 4.9.x [1] (see -fsanitize=undefined option and its suboptions). However GCC 5.x has more checkers implemented [2]. Article [3] has a bit more details about UBSAN in the GCC.

Each bank (chip select) is dynamically mapped to the CPU-viewed address base via the bus controller. The bus controller must be configured before any access to the bus. This driver parses the "ranges" property of the System Bus node and initialized the bus controller. After the bus becomes ready, devices below it are populated. Note: Each bank can be mapped anywhere in the supported address space; there is nothing preventing us from assigning bank 0 on 0x42000000, 0x43000000, or anywhere as long as such region is not used by others. So, the "ranges" is just one possible software configuration, which does not seem to fit in device tree because device tree is a hardware description language. However, of_translate_address() requires "ranges" in every bus node between CPUs and device mapped on the CPU address space. In other words, "ranges" properties must be statically defined in device tree. After some discussion, I decided the dynamic address reassignment by the driver is too bothersome. Instead, the device tree should provide a reasonable translation setup that the OS can rely on.
