2020-12-04T07:40:52+00:00

The sysfs in batman-adv support was marked as deprecated by the commit 42cdd521487f ("batman-adv: ABI: Mark sysfs files as deprecated") and scheduled for removal in 2021. Signed-off-by: Sven Eckelmann Signed-off-by: Simon Wunderlich

batman-adv: Fix refcnt leak in batadv_store_throughput_override

2020-04-21T08:08:05+00:00

batadv_show_throughput_override() invokes batadv_hardif_get_by_netdev(), which gets a batadv_hard_iface object from net_dev with increased refcnt and its reference is assigned to a local pointer 'hard_iface'. When batadv_store_throughput_override() returns, "hard_iface" becomes invalid, so the refcount should be decreased to keep refcount balanced. The issue happens in one error path of batadv_store_throughput_override(). When batadv_parse_throughput() returns NULL, the refcnt increased by batadv_hardif_get_by_netdev() is not decreased, causing a refcnt leak. Fix this issue by jumping to "out" label when batadv_parse_throughput() returns NULL.

batman-adv: Fix refcnt leak in batadv_show_throughput_override

2020-04-21T08:08:05+00:00

batadv_show_throughput_override() invokes batadv_hardif_get_by_netdev(), which gets a batadv_hard_iface object from net_dev with increased refcnt and its reference is assigned to a local pointer 'hard_iface'. When batadv_show_throughput_override() returns, "hard_iface" becomes invalid, so the refcount should be decreased to keep refcount balanced. The issue happens in the normal path of batadv_show_throughput_override(), which forgets to decrease the refcnt increased by batadv_hardif_get_by_netdev() before the function returns, causing a refcnt leak. Fix this issue by calling batadv_hardif_put() before the batadv_show_throughput_override() returns in the normal path.

batman-adv: Replace usage of strlcpy with strscpy

2019-07-22T19:34:14+00:00

The strscpy was introduced to fix some API problems around strlcpy. And checkpatch started to report recently that strlcpy is deprecated and strscpy is preferred. The functionality introduced in commit 30035e45753b ("string: provide strscpy()") improves following points compared to strlcpy: * it doesn't read from memory beyond (src + size) * provides an easy way to check for destination buffer overflow * robust against asynchronous source buffer changes Since batman-adv doesn't depend on any of the previously mentioned behavior changes, the usage of strlcpy can simply be replaced by strscpy to silence checkpatch.

batman-adv: Fix includes for *_MAX constants

2019-05-25T10:59:53+00:00

The commit 54d50897d544 ("linux/kernel.h: split *_MAX and *_MIN macros into ") moved the U32_MAX/INT_MAX/ULONG_MAX from linux/kernel.h to linux/limits.h. Adjust the includes accordingly. Signed-off-by: Sven Eckelmann Signed-off-by: Simon Wunderlich

batman-adv: Warn about sysfs file access

2019-03-25T09:01:12+00:00

The sysfs files to read and modify the configuration settings were replaced by the batadv generic netlink family. They are also marked as obsolete in the ABI documentation. But not all users of this functionality might follow changes in the Documentation/ABI/obsolete/ folder. They might benefit from a warning messages about the deprecation of the functionality which they just tried to access batman_adv: [Deprecated]: batctl (pid 30381) Use of sysfs file "orig_interval". Use batadv genl family instead Signed-off-by: Sven Eckelmann Signed-off-by: Simon Wunderlich

batman-adv: Make sysfs support optional

2019-03-25T09:01:11+00:00

The sysfs files will be marked as deprecated in the near future. They are already replaced by the batadv generic netlink family. Add an Kconfig option to disable the sysfs support for users who want to test their tools or want to safe some space. This setting should currently still be enabled by default to keep backward compatible with legacy tools. Signed-off-by: Sven Eckelmann Signed-off-by: Simon Wunderlich
