  "message": "adfs: fix E+/F+ dir size \u003e 2048 crashing kernel\n\nKernel crashes in fs/adfs module when accessing directories with a large\nnumber of objects on mounted Acorn ADFS E+/F+ format discs (or images) as\nthe existing code writes off the end of the fixed array of struct\nbuffer_head pointers.\n\nAdditionally, each directory access that didn\u0027t crash would leak a buffer\nas nr_buffers was not adjusted correctly for E+/F+ discs (was always left\nas one less than required).\n\nThe patch fixes this by allocating a dynamically-sized set of struct\nbuffer_head pointers if necessary for the E+/F+ case (many directories\nstill do in fact fit in 2048 bytes) and sets the correct nr_buffers so\nthat all buffers are released.\n\nAddresses https://bugzilla.kernel.org/show_bug.cgi?id\u003d26072\n\nTested by tar\u0027ing the contents of my RISC PC\u0027s E+ format 20Gb HDD which\ncontains a number of large directories that previously crashed the kernel.\n\nSigned-off-by: Stuart Swales \u003cstuart.swales.croftnuisk@gmail.com\u003e\nCc: Russell King \u003crmk@arm.linux.org.uk\u003e\nSigned-off-by: Andrew Morton \u003cakpm@linux-foundation.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@linux-foundation.org\u003e\n",
