* Rename struct device_d to deviceSascha Hauer2023-01-101-5/+5
| | | | | | | | | | | | | The '_d' suffix was originally introduced in case we want to import Linux struct device as a separate struct into barebox. Over time it became clear that this won't happen, instead barebox struct device_d is basically the same as Linux struct device. Rename the struct name accordingly to make porting Linux code easier.

* fs: jffs2: fix error when reading blocks with offsetHolger Assmann2022-02-081-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | This bug resulted in a panic when trying to read a file partially with an offset, e.g. when starting Linux. In such a case a header is loaded by a separate call of jffs2_read(), which then copies only the first n bytes out of the respective block. When the remaining data of the block is then subsequently going to to be read the system deviates in its behaviour from that under Linux by not calling jffs2_read_inode_range() in a 4k-alignment, but with an offset. jffs2_read_inode_range() originates from the Linux jffs2 driver. When being called with an offset it still reads 4096 bytes of data and eventually returns fragments of two consecutive blocks. jffs2_read() then reads this result whilst again applying the offset, therefore returning faulty data. We fix that problem by calling jffs2_get_block() without an offset and therefore reading the whole block. The offset is then applied when we actually perform memcpy with the returned buffer. This fix might also increase the performance since the respective block is likely to be cached from the previous call.

* fs: jffs2: remove unnecessary slab cache structureHolger Assmann2021-11-303-124/+20
| | | | | | | | | | | | jffs2_create_slab_caches() and its subsequent kmem_cache calls are not needed in Barebox since they can directly be replaced by malloc calls.

* fs: jffs2: introduce reference counting at probeHolger Assmann2021-11-301-12/+22
| | | | | | | | | | | | | | | | | | | | | | | The Barebox jffs2 driver initialises global slab caches and compressors within the probing stage [1]. In Barebox, jffs2_create_slab_caches() has several calls to kmem_cache_create() which does nothing more than allocating the context data structure for the kmem_cache. Probing a second jffs2 however will overwrite the original pointers returned by kmem_cache_create(), leading to a double free when more than one jffs2 file system gets unmounted and jffs2_destroy_slab_caches() is called. The same issue exists regarding jffs2_compressors_init(). We can fix this bug by introducing reference counting for both the slab caches and the compressors so that the global data structures are kept as long as at least one file system is present.

* Add support for a saving build objects in a separate directory.Marian Balakowicz2006-09-011-7/+9
| | | | | | | | | | | | | | | | | | | | | Modifications are based on the linux kernel approach and support two use cases: 1) Add O= to the make command line 'make O=/tmp/build all' 2) Set environement variable BUILD_DIR to point to the desired location 'export BUILD_DIR=/tmp/build' 'make' The second approach can also be used with a MAKEALL script 'export BUILD_DIR=/tmp/build' './MAKEALL' Command line 'O=' setting overrides BUILD_DIR environent variable. When none of the above methods is used the local build is performed and the object files are placed in the source directory.
